Ilove the dollar store. I use it to teach my little one (age 3) about money. He doesn't get much allowance but he can spend a dollar every month or so if he saves and so far he hasn't outgrown the stuff there. He is learning about value also. Some stuff breaks too soon and he notices (of course the loud stuff he buys lasts and lasts and ...)
I buy little stuff for my teenage grandsons like silly string and those balls that spark when clacked together. I have found cool toys there that cost more elsewhere. I have also found junk and things that cost more there like mixes for 88 cents that they sell for a dollar. I buy all my packing tape there now and it works fine. I buy bubble bath there and some shower stuff (I mean party shower) I make bags or baskets of stuff as gifts. I just bought Bible stories for in the car that my DS2 likes and they are the only place that sells a phone case to fit my DH phone for under 10 bucks. Yes it wears out in 6 months but I am still ahead. I like dollar stores. OUr local Family Dollar is closing so I am enjoying some really good sales there as well.
