They also lose mail too. I once paid a bill and it never got paid. Then the following month I get a bill that's two months charge plus a $20 late fee for the previous month. The lost check was never cashed.
I've seen all the clearance sales there too. Unfortunately there's nothing there I have to have. The best deal I once got from HL was when they had the Testors 1/4 scale visible Dodge Hemi kit. Someone had posted that day about a 50% coupon that HL had. So I printed and went to HL to see what I could find. I grabbed a Hemi which was marked at $70. So I got it for $35. They had 3 of those kits. Two were marked at $80 and one was marked at $70. So I got a good deal. I still haven't built it yet.
