(and other 72-pc Copic marker sets at Staples)
If I'm not mistaken, these are premium marker sets that are supposed to be worth hundreds and hundreds of dollars, yes? All price research comparisons I can find suggest that $15 would be reasonable for 2-3 of those markers, not 72.
My friend's card was already charged by Staples, but there is no assurance they won't still nullify the order and refund him. Still worth a shot unless I'm totally off-base.
