Thrift Store Flipping — Buy-Below Before You Fill the Boot

We have 41 data points on New Balance 550.

Charity shops and car boots are where the best margins live — you can buy at a few euros and sell at twenty. But they're also where most beginners fill their homes with unsellable stock. Here's the discipline that separates the two.

Have a target list before you go

Walking in and 'seeing what's there' is how you buy junk. Go in knowing the brands and models that actually sell, and what you can pay for each. Brands clearing fastest right now is that list.

A short list of 10–15 target brands turns a two-hour rummage into a fast, focused scan. If your list leans older or one-off pieces, spotting genuinely valuable vintage is a separate skill worth learning before you buy.

Know what sells before you buy

Demand + whether to buy before cash sticks.

The 30-second check

Brand label → condition → size → price. If any of the four fails, put it back. Most items fail on size or condition.

Check seams, armpits, collars and hems for wear. Check zips work. A flaw you miss is a return you'll pay for.

Know your number before you queue

The buy-below price decides everything. If the tag is above it, walking away IS the profitable decision. What actually left the shelf this week is the public average.

Resale IQ gives you that number per item from 5,330,000+ listings across 5 EU markets, so you can check on your phone in the aisle instead of guessing.

Frequently asked questions

What should I look for when thrift flipping?

Recognisable brands in good condition and common sizes, priced below your buy-below number. Check labels, seams, armpits, hems and zips. If brand, condition, size or price fails, put it back.

How much should I pay at a charity shop to resell?

No more than your buy-below price — roughly the item's average sale price × 0.95 (after fees) × 0.70 for about a 30% margin. Anything above that is speculation.
