Sam's Club offers $1-a-week membership

If you've been thinking about joining a warehouse club, but don't know if it would be worth the membership cost, Sam's Club is looking for you. The retailer is offering a $10 trial membership for 10 weeks, starting October 17. All you have to do is show up at one of the club's locations and sign up.

Now, whether or not you should join a warehouse club has long been a debate of personal finance-minded websites. Do they save you money or cost you money in the long run? WalletPop's experts have long decided that these memberships can be worth the costs if you shop carefully and buy items that actually costs less to buy in bulk, that you are not buying too much and wasting food, and that you use it often enough to make sense.

So where does Sam's Club rate? On the latest comparison we've run, it ranked second after BJ's, but only by a few pennies on a set shopping list.
