when i picked up my online order, there was just a simple signing of the order receipt, no CC check or anything, so i didn't get to use my $10 coupon, although i didn't ask either

the fine print on the coupon does say 'You must present this coupon at time of purchase' and mentions 'in-flight duty-free shopping' so i would think it's a no for online orders, was anyone able to double dip on the 15% off and using the coupon? (or other duty free specials online)
