The Amazon Fire HD 8 is the stronger starting point if its apps meet your needs; the onn 7-inch Core is an Android alternative with very little room left for tax. At our October 4, 2026 research check, Best Buy’s black 32GB Fire HD 8 (2024) listing showed US$54.99, while Walmart’s Mocha 64GB onn 7-inch Core (2026) listing showed US$97.
These are dated advertised item prices, not a promise that either offer is available in your area or that the final total stays below $100. A strict all-in budget needs a checkout check that includes tax, delivery and essential accessories.
We researched exact retailer listings and manufacturer documentation. We have not tested these tablets. Prices, seller, stock, promotions and delivery options can change; app availability also depends on region and software.
The shortlist at a glance
| Exact option researched | Observed US item price | Best reason to consider it | Main limitation |
|---|---|---|---|
| Amazon Fire HD 8, 2024, black, 32GB, model B0CVDN4QS6 | $54.99 at Best Buy | Leaves room in the budget for tax or a case | Amazon Appstore; Google Play is not supported |
| onn 7-inch Core, 2026, Mocha, 64GB, Walmart item 18567405463 | $97 at Walmart | Compact Android tablet with more built-in storage | Low-resolution screen; tax can take it over $100 |
Both prices were checked October 4, 2026, on standard product listings rather than used or open-box offers. Delivery availability shown by a retailer can depend on its selected location. Confirm the condition and seller again before ordering.
1. Amazon Fire HD 8: best starting point for Amazon-compatible entertainment
The exact Best Buy listing, SKU 6601644, identifies an 8-inch 1280 × 800 screen, 3GB RAM and 32GB storage, with optional microSD expansion up to 1TB. The offer was sold by Best Buy when checked.
Our preference at this price is an editorial judgment about the available budget, not a speed-test result. It leaves substantially more room than the $97 option for a protective case or other essentials.
Check the apps first. Amazon’s Fire OS documentation explains that its devices do not use Google services in the same way as conventional Android tablets. If school, work or a favorite app requires Google Play, do not assume a Fire tablet will meet that requirement. Check the Amazon Appstore and the app developer’s supported devices.
A browser version of a service may be enough for occasional use, but it can behave differently from the app. Test sign-in, video playback and downloads instead of assuming the website replaces every app feature.
2. onn 7-inch Core: a compact Android option close to the ceiling
The Walmart listing for the Mocha onn 7-inch Core specifies the 2026 model, Android 16, 64GB storage, microSD support and a 7-inch 1024 × 600 LCD. The page showed $97, sold and shipped by Walmart.com, at our check.
Consider it if you specifically want a small Android device and can confirm your essential apps work on the exact model. Its low-resolution screen is the main compromise: dense web pages, small spreadsheet cells and full newspaper pages give you little room to work.
The box list includes a USB charging cable but does not list a wall charger. Check whether you already have a suitable adapter and include any required purchase in the total. We did not verify a published long-term update endpoint, so ask for that information rather than treating the launch Android version as a support guarantee.
Budget warning: $97 leaves only $3 before reaching $100. This is an under-$100 sticker-price option, not a reliable under-$100 all-in recommendation.
How to keep the whole purchase below $100
Write down a total budget before comparing sale labels. Use this calculation:
Tablet + sales tax + shipping + required charger or case = your actual cost.
For illustration, if sales tax were 8% and shipping were free, a $97 tablet would cost $104.76 before accessories. The $54.99 tablet would cost $59.39. Those are arithmetic examples, not quotes for your address; local tax treatment can differ.
At that same illustrative tax rate, a tablet-only price would need to be about $92.59 or less to fit a $100 all-in ceiling. If a seller adds shipping, lower that target again. Treat memberships, installment payments and subscription trials separately from the cash price.
What to expect from a low-cost tablet
Prioritize one or two everyday jobs
A simple reading, browsing or video device is a more realistic goal than a replacement for a laptop. Make a short list of essential tasks: one streaming service, one reading app and video calls, for example. Verify those before comparing cameras or bundled extras you may never use.
Storage capacity is not working memory
The 32GB or 64GB figure describes storage for the system, apps and files. It is not RAM, and some of that capacity is already occupied. A memory card does not automatically increase working memory or let every app move off internal storage.
Screen size and sharpness are separate
A larger diagonal can make buttons easier to target, but it does not guarantee clearer text. Try a familiar article at the font size you actually need. If you continually pinch and zoom, the low price may not compensate for the inconvenience.
Support and returns deserve attention
Record the retailer’s return deadline and any condition requirements before opening the box. During that window, check Wi-Fi in your normal room, charging, speakers, touch response, camera calls and the apps you need. Also check available system updates.
Should you buy used instead?
A used tablet can offer a better screen or processor for the money, but compare it as a separate category. Look for the exact generation, battery condition, remaining update support, included charger, seller warranty and normal return rights.
For an iPad or Android tablet, confirm it can be set up without the previous owner’s account or an organization’s management restrictions. Avoid “for parts,” activation-locked and school-managed units unless that is explicitly the project you want. A low price does not resolve those limitations.
Frequently asked questions
Is a $99.99 tablet within a $100 budget?
Only if the complete payable total stays within it. Tax or shipping can put it over immediately. Decide whether your limit means the advertised item price or everything you must pay.
Which option is better for Google apps?
Start with a conventional Android tablet and verify the exact apps on the exact unit. The Fire HD 8 is not the right assumption when Google Play support is a requirement. Do not make an unsupported software workaround part of the buying plan.
Can these tablets handle schoolwork?
Only after the school confirms the required apps, browser features, account policies and assessment software. A tablet that plays video may still be unsuitable for a particular assignment or examination.
What is the best choice if neither passes those checks?
Keep using an existing device, compare a returnable refurbished option or save for a model that meets the actual requirement. Spending the full $100 on an incompatible tablet is worse value than waiting.
