[quote name='bthoma']And the coupon clearly states that it can only be used once per member account, so making your cashier read it closely won't exactly encourage them to let you use it multiple times...[/QUOTE]
It also says it's for "membership purchased between August 23, 2010 and October 27, 2010" . . . I've been hesitant to try it because my membership expires at the end of this month, so every time they ring me up they get a message telling them to ask me if I want to renew. I really don't want to renew right now -- my current membership will last me through this sale, and with the future of B&N in a bit of a flux I'm not inclined to invest in another year right at this moment (I really only get my money's worth out of the membership with these Criterion sales, so I might as well wait and see if there's another one). But it makes it pretty obvious to them that I'm not within the coupon terms.
I dunno, I may be overthinking it. But last year when I was a new member and could use the coupons entirely legitimately, I remember encountering several cashiers that read over the terms pretty closely before accepting them, and others who already knew the terms without having to look at them. Maybe the managers around here are more on top of educating their employees about the coupons than in other areas.
