Another valuable item that’s often overlooked at the thrift store is mugs – particularly the older ones. If you can find a vintage mug from a well-known brand, like Starbucks for example, or one that features a well-known character, like Snoopy for example, then you could make a good profit on it. So, next time you’re at the thrift store, take a look at the old mugs. You never know, you might find a 60 cent mug that you can sell for ten bucks on eBay.
