Get a new Costco membership or upgrade, a $105 value, for $55 via Zulily. Along with the membership, you'll also receive $50 worth of coupons including a free rotisserie chicken, free 48-pack of batteries, free 35 count case of Kirkland Signature water, and more. The membership cards and coupons will arrive in the mail. Current members can use the card for an upgrade - it cannot be used for renewal. Please note, you must be a member to access the sale, but sign up is free and easy. There is no sales tax (except KY, NV, OH, WA).
