Or, more likely, someone will jump in front of that request for 50% and ask for 45%. Then 40%, then 30, then 20 and then 8%. It's a market. I do agree, though,

Or, more likely, someone will jump in front of that request for 50% and ask for 45%. Then 40%, then 30, then 20 and then 8%. It's a market. I do agree, though, that those very high discounts should be a red flag, if they're for any serious money. Stuff for $5 with a 50% discount is no big deal if someone just wants ot be rid of a card and doesn't mind losing a couple bux, which they'd end up paying in fees buying BTC anyway.
