Do you mean shopping at thrift stores? There are only two in the area where I live, and I would give them both a low rating on deals and selection of needed items. I bought a couple of things recently, past couple of days, where I paid more than I wanted to only because I didn't want to wait for a better deal to happen by.

I bought a pair of shoes almost a year ago, but only started wearing them last month. The bottom came loose, unglued or something. The store wouldn't take them back but did try to sell me glue to fix them as they still look new. I might buy the glue and try to repair the shoes, but not at that store.

Hard to say what the best bargin I found would be. No one wants to pay more than they have to, often they unknowingly spend more in time and effort in the search, than they would if they just took the fastest and most direct course. Hope this helps and remember, you can't take it with you.
