a. Dollar stores are 98% junk. I never darken the door.

b. Big Lots can yield some good bargains if you know brands and prices. I get Wasa bread there for about 2 bucks a package. I found Balsamic vinegar for 2 bucks ( Heinz) and Lubriderm with spf 30 for 5.50 - I know it sold for about 15 bucks in drugstores. Shower gels - about 3 bucks for national brands. So, maybe the scent has been discont'd, but what the heck.
Watch out tho for dirt cheap toiletry items - the Made in China is usually in tiny, well hidden print.
They had six packs of V-8, the low salt ones, and by the time I went back the next day - gone. I wanted them for a trip.
