T206Collector...bumps are okay on for sale items if you are lowering your price with each bump. Beyond that, you shouldn't get to bump for a number of days, perhaps a week even.
I also think a purchase on ebay followed by a sale on the B/S/T is not wrong, immoral or otherwise unethical. If you notice that a guy is trying to flip for profit, you don't have to buy it. Just pat yourself on the back for a job well done, knowing that the asking price is likely higher than the market value.
