These examples will show you the definition of thrift store sniping.
I share these for ideas and to inspire to help YOU make more money for more freedom.
I usually focus on recycling for profit for the bigger picture, but thrift occasionally for kicks. I score good finds with relative ease because I have a lot of experience and a trained eye. This can easily be developed with practice.
Many people say they don't have access to curbside recycling, so here's your alternative. Thrift stores are great for generating additional income if you source wisely.
During my prime, I'd hit 15-20 stores a day on foot/public transportation in my city. Yea, I know how to hustle... and that's why it paid so well.
If you just go to a few stores on a rotation each week, you can easily make a few hundred dollars in profit each month as a complete beginner. That's not too bad. Of course, your success will breed more success, and then it'll be an exciting new income stream.
Buy low, sell high.
Be confident in setting a price you feel good about and waiting for the right buyer to come along. Adjust as necessary, not because you want a quick return.
5 quick flips from some casual thrifting.
Sealed Scrabble game bought for $11, sold online for $95 in my city in under 24 hours.

Sonos media streamer bought for $5. It wasn't working, so I went home, listed it for parts, and took a nap. It sold it online for a "discounted" $75 while I was fast asleep, only 2.5 hours after buying it!
It's worth $200 if it worked, but the fuse on the motherboard was likely melted.

Sealed printer toner bought for $15, sold online in under 12 hours for $80. These almost always sell immediately if priced right.

Popular compact printer bought for $22, tested and sold for $135 in under 24 hours.

Graphing calculator bought for $11, sold for $64 in 12 hours. These sell like water and are almost like finding straight cash.

That's $64 spent to generate $449 in revenue. That's a 7x. Net profit after costs, fees and shipping was $265 for a 4.14x. That's not too exciting for me, which is why I prefer recycling for profit with $0 in costs, and more cash deals to completely avoid fees or shipping.
As you can see, some items are new, some are used, and one didn't even work. Everything has a resale price, and sometimes it can be surprising. That's why you look everything up until you get comfortable with the general items and brands you find on a regular basis.
When you find items at thrift stores, go to eBay's app and scan any barcodes in to see what it's selling for. If you filter on recently sold items, you'll see the actual prices, not what people are asking for it.
