In a thrift store you have about ten seconds to decide if something's worth buying. A price checker app tells you what it actually sells for, not what people are asking.

What a price checker app actually does

• Identifies the item, from a photo or a search

• Shows recent sold prices, not asking prices

• Gives you a range, so you can decide whether the margin's there after fees

Three ways to check resale value (fastest first)

1. Photo scan (seconds). Snap the item in Hero and get a resale value from real resale data. Best in the aisle and for whole hauls.

2. eBay sold listings (1–2 minutes). Search the item, filter by Sold items, match condition and ignore outliers. Free and reliable, just slow. Here's the full method.

3. Free price guide. Browse Hero's price guide for electronics, phones, video games, toys, furniture and more.

The 10-second buy-or-pass rule

Take the low end of the sold range and subtract fees, shipping and what you'd pay. If what's left is a profit you're happy with, buy it. If not, put it back. Fees vary by platform and category, so check them first: eBay fees explained.

What to look for in a price checker app

• Uses sold data, not asking prices

• Works from a photo, because typing model numbers in an aisle is slow

• Lets you go straight from price to listing
