My wife was very kind to let me get these. She's very conscious about the "bargains" I go after

Someone had donated a decent collection of CDs to the Salvation Army. ("Decent" to me means 70s and 80s rock; your tastes may differ.) This thrift store is reasonably priced; they were selling the CDs for $2 apiece -- just a tad too much to grab them all.

So I asked the cashier if I could make an offer on all of them. We got all 107 of them (plus or minus) for $1 apiece. There were some duplicates, but we can re-gift those or re-sell them (CDs go for $2 usually at flea markets around here.) We got the CDs for the cost of one song on iTunes!

These guys would bargain. Some other ones in the area are firmer on their prices. Doesn't hurt to ask, though!
