Good afternoon, floodgater,
Welcome to the Best Buy forum!
That sort of error when trying to activate a My Best Buy related coupon usually means the member has more than one rewards account and a merge is needed. The coupon is tied to a specific rewards account, and if that rewards account isn't linked to your BestBuy.com account, then you'll get an error message. You may not even know you have more than one rewards account; however, a merge is a great option when a member happens to have more than one rewards account, as it's just easier to have everything in one place. Please send me a private message with the details listed below and I'll see what I can do to further assist.
