We have access to "Dollar Tree". "Dollar General" and another one (I can't think of the name right now). Dollar Tree is my favorite though.
Let's see. I don't go that often, but I find that seasonal items are a good deal. I also scour their bath and body section. I found some really wonderful body wash, lotion and body butter there at Christmas time. It rivals scents from Bath and Body works.
I also like the hand soaps, the hair accessories, socks, nail items.
A few years back I bought some of the big latte cups there to use for soup cups. (We don't drink coffee) They are still going strong. I have also bought a few ceramic plates there to supplement the kitchen ware. Nice colors.
I don't think many of the cleaning products are a good deal there, but all of the party stuff is, including wrapping paper, etc...
In the past I have also purchased plastic storage containers. If I don't lose the lids they are suprisingly good quality. I actually prefer to use real glass to drink from and sometimes their glasses are ok. I find them cheaper at Walmart most of the time though.
Every once in a while I find a decent book there and purchase those for gifts. Office supplies are usually pretty good.
Sometimes I get candy there, but not always the best deal anymore.
I guess that's about all I can think of right now.
