With the economy in the current state of uncertainty, I think most people are trying to watch their spending and looking for ways to save a few bucks here and there. If you haven't thought of it before (or just never knew much about it), I would recommend looking into a warehouse membership. These places usually have some great savings on items that you buy frequently anyways. May not be the place for you if you're single and don't have a lot of room but for a couple or a family, it's a really great investment. Most memberships run about $40-$50/year (may depend on location) but give you access to mega savings. You can buy everything from toothpaste to diapers to fresh fruit to books to furniture to big screen TVs to clothes to tires etc. etc. Many of them also offer gas stations - a major bonus these days as the cost of gas keeps rising. This list is not exhaustive but here are some of the big ones that I'm familiar with - check them out to see what's in your area (and if you have any others to list, please comment on this post).
