Living Social offers a new Costco Membership bundled with a $20 Costco Cash Card and coupons for a rotisserie chicken, 48-pack of batteries, case of Kirkland Signature water, $4 off Kirkland Signature coffee, and $4 off Kirkland Signature albacore tuna for $55. That beats our mention from December, when we saw a new membership bundled with fewer coupons and no cash card for the same price, and is the best membership deal we've seen for Costco. Deal ends February 9.
