As far as getting inexpensive items goes, this isn’t really worth the trouble or the thrill of some sort of auction hunt. Just looking through Tophatter my first go, a bunch of red flags popped up. One thing for sale was a tablet, but the specs for it were terrible, and with all their electronics, similar things seem to go on. Camera drones with only 2MP cameras, for instance. They also sell ambiguously collectible coins and items that seem to have value, but don’t at all list their composition or minting information. Jewelry doesn’t have anything about it’s makeup either, which tells me that it’s certainly not high quality.
Also, the site doesn’t really have much for sorting algorithms. You have a few tabs to search through, and if your product isn’t there, tough luck, check in again after 5 minutes and some auctions pass.
If you want to get a bunch of inexpensive goods, just use an app like Wish instead, because at least they list it at one price and that’s that, no competing people who might not know exactly what they’re buying, a wider selection, and at very least, it has a properly working search function.
