Looks like the Sam's club gift cards can be used at Sam's gas stations as well. So a $60 fill up (6x$10 cards) nets 3000 miles for those with the 2x/1000 bonus. This assumes sam's club reports the transaction to e-mall, which then reports it to UA, as 6 separate $10 gift card transactions. Is this risky?
