Buying in bulk is definitely a help when it comes to keeping you out of the store, as well as keeping from running out of the basics. However, it can also be more than some can afford, especially if it involves a membership to a big box store.
Memberships to places like Sam's Club, Costco, and BJ's can run upwards of $100 a year. While you may well save that much or more inside of a few months, the upfront fee can be too much for one family to afford. One way around that is to share the membership, and therefore the cost, with a family member, friend, or neighbor. You don't have to shop together if you don't want to or if its not convenient because you will both have your own membership card. This makes it much more feasible to obtain the savings. Another help when purchasing a membership is doing it around tax refund time or when you usually get a bonus from work, etc. If it comes out when you get a refund its not affecting the budget and bill money.
These clubs have their perks, including savings on things such as gas, which is often 5-10 cents per gallon cheaper. Some, such as BJ's, accepts manufacturer coupons in addition to their own. There are also other perks, including discounts on some services such as car insurance and car rentals. While it makes no sense to buy 3 dozen eggs if you don't eat more than 2 a month, stocking up on diapers when you have a baby does, and if you're saving money, well, that makes even more sense.
The best bet is to use the free shopping passes that most all of them offer and try them out. Compare prices, see what they have to offer, and then decide which one, if any, would be the best choice for your needs and budget. I've included the links below for your convenience to read about each one, their membership policies, plans, and prices. You can also check their locations and hours.
So, until next time, Happy Saving!!
