I remember Turbo Lister! I started selling things on eBay 20 years ago at this point. I used to be able to go into basically any used record shop and find a dozen records to flip almost instantly.
The rest of the world got wise to that and now gems are hard to find. I mostly just sell old things I don't need now, so it's one at a time. I haven't had to try to list a bunch at once lately. I feel like their fees got goshdarn ridiculous.
Luckily I have PeakMonsters to help me with selling my Splinterlands cards. :)
