Donate them to homeless shelters! Last night we had an electrical sub-station go out, and our city and several nearby towns were out of electricity. I volunteer at our women's shelter, and I was thinking that I wasn't sure what they're doing because I don't know that they have enough candles for everyone. It'd be nice to have a stash just in case.
ETA: The reason for reading the thread in the first place --- how did you get started with couponing? Just picking up the Sunday paper? I know I can do online coupons, too. How long did it take you to begin seeing savings? I recently set a fairly strict budget for us. We buy groceries every 2 weeks. I guessed on the grocery budget (because we were spending tons on going out to eat). We went over by $43 for the 2-week period, so if I could save $25 a week with coupons, that would be awesome!
We are in the same boat as some others in that we don't have any stores that double, triple, etc., and I've never seen coupons for lots that we buy. I hadn't thought about using overages, but that could be a good way to go - and somehow thrilling! I could get DC to help with the process, too.
