Yeah, not accepting escrow is a huge no-go. If you want to accept escrow I will buy some Amazon gift cards from ya.
There is no such thing regardless, if they used a escrow.
Think about it, if they sell at dirt cheap prices - youre ignoring the obvious on how it was obtained and knowing the card will go bad within 24hrs.
There are many ways of obtaining it, and they are usually obtained by someone refunding or such.
Not the best way or quality of goods to be buying though.
