You can use the bot to your advantage. I do it with the low overall Topps now series. Say you have one at qs buy price of 1875 and the sale price is like 3k. If you put in a buy of about 2500 the bot will put up a price of 2501. If your buy price is too high in relation to the sale price the bot won't bid. Sell to it and cancel your buy order. It'll then put in a sell price of 2999. You can put in a sell as low as 1900 and it will still undercut you despite it selling at a loss Buy the bot card at 1899. You can do this over and over. It's not a lot of stubs, but it's easy. The only risk you run is somebody else comes in and takes your bids while you're waiting the few seconds it takes for the bot to change its bid. However, there isn't a lot of action on these older cards so it doesn't happen very often.
