OneScan is a real-time price comparison tool that lets you scan any barcode and instantly see prices across Amazon, Walmart, eBay, Best Buy, and Kroger. But there's more than one way to use it. Here are five scenarios where OneScan helps you save money and shop smarter.
Save Money on Everyday Shopping
The most common use case: you're in a store, holding a product, wondering if the price is actually good. Instead of guessing, you scan the barcode and know instantly.
Open OneScan and point your camera at any barcode
View real-time prices from Amazon, Walmart, eBay, Best Buy, and Kroger
See price history and determine if now is the right time to buy
Tap any retailer to buy directly or keep shopping in-store
I found a kitchen mixer for $89 at Target. OneScan showed me Amazon had it for $59 with Prime shipping. Saved $30 in 5 seconds.
The goal isn't always to buy online—sometimes you just want confirmation that the in-store price is fair. Other times, you'll find significant savings elsewhere.

Product Flipping for Profit
Retail arbitrage—buying low and selling high—is a legitimate side hustle. OneScan turns casual shopping into a treasure hunt for profit.
The 3x Rule: If you can sell an item for at least 3 times what you paid, buy it. This buffer covers platform fees, shipping, and occasional returns.
Browse clearance sections, thrift stores, or garage sales
Scan everything with a barcode—even items that look worthless
Check the resale value across all platforms
Buy when the math works, skip when it doesn't
Found a KitchenAid mixer at Goodwill for $35. Scanned it—selling for $180 on eBay. That's a $120+ profit after fees.
Flippers who use OneScan make faster, more confident buying decisions because they're working with real data, not guesses.

Quick Purchase Access
Sometimes you already know what you want—you just need to buy it fast. Scan the barcode of a product you've run out of, and OneScan takes you straight to the purchase page.
Scan the barcode of the product you need to reorder
Compare prices across retailers in one view
Tap the best option to go directly to that retailer's product page
This is especially useful for:
- Household staples you reorder regularly
- Products you've tried and want to buy again
- Gift ideas you spotted at someone's house
No searching, no typing product names, no sifting through wrong results. Scan and buy.
Find Nearby Stores
Sometimes you need something today—shipping won't cut it. OneScan shows you which retailers have the product in stock, helping you decide whether to order online or drive to a store.
When in-store makes sense:
- Urgent purchases where same-day matters
- Large items where shipping costs are high
- Products you want to inspect before buying
- Returns are easier in-person
