Why don't people learn?  Nobody, I mean nobody has an endless supply of 50% off gift cards/codes.  Nobody.  Ever.  It always is a scam.  Period.

Now someone selling a SINGLE gift card ("hey I got this stupid Best Buy card and I never ship there 50% off OBO") might not be a scam but someone saying "Hey I got an unlimited supply of $100 BB gift cards for $50 in BTC" is always a scam.  Strangely it always works.  Also escrow is no protection from this type of scam.  As seen the scammer will gladly accept escrow because he has every intention on delivering a code ... it just happens to be a code purchased with a stolen credit card.
