First & best advice, go early.. like right when the store opens. The line starts to build up real quick. Women will find better bargains and deals. The store is 70% women, 20% men, & 10% other stuff.
Really not going to repeat what other people are saying. We have heard of the deals from back in the days, not so much now. I believe Last Chance is pricing a lot of the items by brand despite the condition they are in, which is a little insane. You can definitely find better deals on eBay.
Your only choice is to get there early because there are resellers that are there bright and early and grab the good deals by the cart. You can sometimes get lucky when the do there sporadic restocks. Patience is key.
