It seems as though prices are constantly on the rise these days. One way to help defray increasing costs is by shopping at a warehouse outlet, which allows you to buy everyday items in bulk and save on everything from gas to big-ticket items like electronics and kitchen appliances. Costco Warehouses is one popular and beloved option, though you need a membership to shop there. A standard Costco Gold Star annual membership costs $60 per year, but if you buy it via StackSocial right now, you'll get a free $20 gift card, essentially bringing that price down to $40. If you opt for the executive version of the membership, which offers a reward program and better discounts for $120 per year, you'll get a free $40 gift card, effectively netting you a year-long membership for $80. 

StackSocial doesn't list a specific date for when this deal will end, but it must be redeemed by September 8 in order for you to receive your credit. We recommend making your purchase sooner rather than later if you want to take advantage of this offer. Keep in mind, this offer is only available only to new customers, or those whose memberships have been expired for more than 18 months. If you've been thinking of picking up an annual Costco membership, this is a great way to keep more cash in your pocket.

With a Costco Gold Star subscription, you'll get one membership card for your household. It allows you to shop at any Costco warehouse worldwide, as well as online at Costco.com. While Costco is a great place to save on groceries and other everyday essentials, it offers a lot more. A Gold Star membership also means you can use Costco's gas stations and pharmacies, as well as Costco's optical and hearing aid centers. Costco frequently has seasonal plants, decor, furniture, electronics and other products as well.
