Many people want to know exactly where they can buy this alarm clock, what to look for when shopping, and how to compare options. This guide will help you find the best places to purchase the Sharp Big Bang Alarm Clock, compare buying channels, and avoid common mistakes. You’ll also find tips to make sure you get the best value and avoid problems that can happen with online and in-store shopping.
What Makes The Sharp Big Bang Alarm Clock Special?
The Sharp Big Bang Alarm Clock is known for its super loud alarm, making it a favorite for deep sleepers or people with hearing difficulties. It usually features a large, clear LED display, easy-to-use buttons, and sometimes extra functions like a snooze button or battery backup. Some models even have a vibrating feature to help wake you up if you don’t hear the alarm.
People often choose the Sharp Big Bang Alarm Clock for these reasons:
- Loud alarm sound (often over 100 decibels)
- Large display that’s easy to read
- Simple controls for setting time and alarm
- Reliable and long-lasting design
Not all alarm clocks are the same. Many cheaper models look similar but may not have the same loudness or build quality. This is why buying from the right place matters.
Where To Buy The Sharp Big Bang Alarm Clock
You have several options when looking to buy the Sharp Big Bang Alarm Clock. Each channel has its own pros and cons. Here are the main places to check:
1. Online Retailers
Online shopping is the most popular way to buy this alarm clock. You get a wide selection, customer reviews, and often better prices.
Top online retailers:
- Amazon: Probably the easiest place to find the latest models, read reviews, and compare prices.
- Walmart.com: Offers both shipping and in-store pickup.
- Target.com: Sometimes stocks Sharp alarm clocks, especially popular models.
- EBay: Good for finding deals or older models, but be careful about used items.
- Best Buy: Sells electronics and sometimes stocks this brand online.
Here’s a quick comparison of the main online sellers:
| Retailer | Selection | Shipping | Return Policy | Customer Reviews |
|---|---|---|---|---|
| Amazon | Wide | 2-5 days (Prime faster) | 30 days | Thousands |
| Walmart | Moderate | 2-7 days | 90 days | Hundreds |
| Target | Limited | 2-6 days | 90 days | Some |
| eBay | Varies | Varies | Depends on seller | Varies |
| Best Buy | Limited | 2-5 days | 15 days | Dozens |
Non-obvious insight: Amazon usually has the largest selection and fastest shipping, but Walmart often has better return policies, which is useful if you want to try the clock and return it if it’s not loud enough.
2. Brick-and-mortar Stores
Some people still prefer to shop in physical stores. This allows you to see the product before buying and ask questions.
Major stores that may carry the Sharp Big Bang Alarm Clock:
- Walmart (in electronics or home goods section)
- Target
- Best Buy
- Regional electronics stores
However, not all locations have the same inventory. It’s smart to check the store’s website and use the “find in store” tool before visiting.
Tip: Call ahead to make sure the clock is in stock. Some stores can reserve an item for you for a few hours.
3. Sharp Official Website And Authorized Dealers
Sometimes you can buy directly from the Sharp official website or their authorized dealers. This can be a good way to avoid counterfeits and get warranty support.
- Sharp official website: Sometimes offers direct sales or a list of trusted dealers.
- Authorized dealers: These are often listed on Sharp’s website. Buying from these stores can help with warranty issues.
Non-obvious insight: Buying from authorized dealers can make it easier to get customer service or exchange your clock if there’s a defect.
4. Specialty And Niche Retailers
Some stores focus on products for people with hearing loss or deep sleepers. These include:
- Harris Communications
- Sonic Alert
- Hearing loss specialty shops
These retailers may carry the Sharp Big Bang Alarm Clock or similar loud alarm clocks. They often provide expert advice.
Comparing Online Vs. In-store Shopping
Both online and in-store shopping have strengths and weaknesses. Here’s a direct comparison to help you choose:
| Factor | Online | In-Store |
|---|---|---|
| Selection | Wide (many models) | Limited (few models) |
| Price | Often lower, frequent sales | Usually higher |
| Shipping | Wait for delivery | Take home instantly |
| Ability to test | Cannot test before buying | Can see product, but rarely test alarm sound |
| Returns | Must ship back | Return directly at store |
Experience-based tip: If you need the alarm clock urgently—perhaps you have an important exam or work shift coming up—buying in-store or using same-day delivery (offered by Amazon or Walmart in some areas) can help.
What To Check Before Buying
Not all Sharp Big Bang Alarm Clocks are the same. Here’s what to look for:
- Model number: Check if you are getting the latest version. Some old models lack features like battery backup or extra-loud volume.
- Alarm volume: Look for decibel ratings. The best models are over 100 dB.
- Display type: LED is the easiest to read, especially at night.
- Power source: Some use only wall power; others include battery backup.
- Warranty: Buying from official or authorized sellers usually includes a warranty.
- Extra features: Do you need a vibrating pad, USB charging, or a special snooze function?
Common mistake: Some people buy a “Sharp” alarm clock but not the Big Bang model. Always check the product title and description.

How To Spot Counterfeit Or Fake Products
Counterfeit products are a growing problem on online marketplaces. These fake clocks may look similar but are often lower quality and much less reliable.
Ways to avoid counterfeits:
- Buy directly from well-known retailers or the official Sharp website.
- Check for “sold by” and “shipped by” on Amazon or Walmart listings.
- Read customer reviews—watch for many negative comments about poor build or low volume.
- Make sure the packaging has official Sharp branding and warranty information.
Price Range And Value For Money
The price of the Sharp Big Bang Alarm Clock usually ranges from $20 to $40 in the US. Prices can go higher if you want extra features like a vibrating pad or a larger display.
What affects the price:
- Newer models with more features are more expensive.
- Specialty versions (for hearing impaired, for example) cost more.
- Sales and discounts can lower prices, especially around holidays.
Example: During Black Friday or back-to-school season, Amazon and Walmart often have discounts of 10–30%.
Shipping, Returns, And Warranty
Shipping
- Standard shipping: 2–7 days, depending on the retailer and your location.
- Expedited shipping: Costs extra, but can arrive in 1–2 days.
- In-store pickup: Some stores let you order online and pick up in person the same day.
Returns
- Amazon: 30-day return window; easy to print a return label.
- Walmart/Target: Up to 90 days for returns; you can return in-store even if you bought online.
- Best Buy: Shorter return window, usually 15 days.
Warranty
Most Sharp Big Bang Alarm Clocks come with a 1-year limited warranty. Keep your receipt or order confirmation for warranty claims.
Practical tip: Take a photo of your receipt or email confirmation. This makes warranty claims easier if you lose the original paperwork.
Comparing The Sharp Big Bang Alarm Clock To Alternatives
There are other loud alarm clocks, but not all are the same quality or value. Here’s a quick side-by-side comparison with two popular alternatives: the Sonic Bomb and the Peakeep Twin Bell.
| Feature | Sharp Big Bang | Sonic Bomb | Peakeep Twin Bell |
|---|---|---|---|
| Alarm Volume | ~100 dB | ~113 dB | ~90 dB |
| Display Type | Large LED | LED + Vibration | Analog |
| Battery Backup | Yes | Yes | No |
| Vibrating Pad | No (some models yes) | Yes | No |
| Price Range | $20–$40 | $30–$50 | $15–$25 |
Key insight: The Sharp Big Bang is great for most deep sleepers, but if you’re extremely hard to wake, the Sonic Bomb’s vibration feature may help. However, the Big Bang is usually easier to set up and less expensive.

Top Tips For Getting The Best Deal
- Set price alerts on Amazon or Walmart to get notified of sales.
- Check for coupons on retailer sites or browser extensions.
- Sign up for newsletters from Sharp or major retailers; they often send exclusive deals.
- Compare models carefully before buying—sometimes a small price jump gets you extra features like a snooze button or backup battery.
- Read recent reviews to see if new models have problems or improvements.
Avoiding Common Buyer Mistakes
Many shoppers make simple mistakes that lead to frustration:
- Not checking the model number: There are several Sharp alarm clocks; make sure you’re getting the Big Bang version.
- Ignoring return policies: If loudness is critical for you, buy from a store with an easy return process.
- Overpaying: Some third-party sellers list the clock for double the normal price. Compare prices before buying.
- Forgetting about power needs: Some clocks require specific batteries or adapters not included in the box.
