As long as the total comes to $10 or more, it doesn’t matter if one item is under $5 and one over – the registers attach one item to one coupon and you’re good since the total is over $10.  I’ve done this a few times now ’cause I need to buy a few pricy items over the next two weeks and this way it’ll cost me very little since I’m combining clearance deals with coupons and paying with bonus points.  Oh, and since they’re all ringing at $10+ a transaction, I’ll hit the $50 beauty 5,000 bonus points that much faster 🙂
