eBay and Amazon could be good places to buy fad items like Fidget Spinners where you can buy one for $1 or more instead of $10-30 like a store like Gamestop, ToysRus, Staples, and grocery stores.
There are also a lot of people who use eBay like kids and trendy people, who follow fads, who got bored of fad items like Fidget Spinners, so you can buy their used spinners from them, and just need to pay for a postage stamp, and bubble wrap envelope to ship it to you by postal mail.
Buying stuff from the dollar store can be risky since some of their stuff is lower quality, and you can't leave a bad review like on Amazon, and eBay where you can sometimes get your money back if you complain to Amazon, and eBay that you got scammed into buying a low quality product.
The staff at the dollar store is not very helpful sometimes, and there is a no refund policy, and you can just exchange it for the same low quality item.
