If the $60 yearly membership fee has kept you from joining Costco, you might be interested in this deal. Now through December 31, Groupon is offering a 1-year Costco membership and a $40 Costco gift card for only $60. The final math on this means you end up with $100 in value and save 66% of your yearly membership! These type of deals are by far the best way to get a the cheapest Costco membership possible.
Even better, this deal is available to both new members OR previous members whose membership has been expired for 18 months or longer. So even if you let your old Costco membership lapse, you'll still qualify as long as it 1.5 years ago.
Once you redeem this offer, you'll receive a digital Costco “shop card” via email. I redeemed a similar offer when I joined Costco earlier this year and my digital card came within a week or two. The card can then be used in-store, online, or at their many gas stations.
