2010 Rebate Check

Costco American Express Business card?

Can you send me a replacement Costco Cash Reward Coupon?

Please contact American Express Customer Service at 1-888-708-8128 for assistance. Reward coupons may be re-issued one time if requested prior to the coupon's expiration of August 31st of the year of issuance. If you find your original coupon after ordering a replacement, please discard one of the coupons because each account is only entitled to redeem one coupon.

I think you're out of luck. Quoted text from costco website. "Using the 2% Reward Certificate

The Reward certificate is mailed with the Executive Member's annual renewal notice. Rewards totaling less than $1 will not be sent. The Reward may be used toward purchases of most merchandise through the front-end registers at Costco warehouses in the U.S. Rewards may be used toward purchases of merchandise only; they have no independent cash value outside of Costco. In the U.S., Reward certificates may not be used: (i) toward purchases of certain merchandise such as alcohol, cigarettes or tobacco-related products; (ii) toward purchases that are not recorded through Costco's front-end registers, such as purchases at gas stations, Food Courts, and online at costco.com; (iii) as payment on Costco Credit Card accounts; (iv) on purchases of services, such as travel and auto; (v) where prohibited by law or regulation; or (vi) on certain other categories as determined at Costco's discretion. Reward certificates will not be replaced if lost or stolen. " Emphasis added by me.
