I recently redeemed $5 in e-rewards for the $15 off each item purchased at FTD. I expected it to come in the form of a coupon code to be entered at checkout, but instead it is a link to ftd.com/anextension. However, miles earning opportunites (at least through Delta) also come in that format. Is there any way around this? I thought that since there were no exclusions and no redemption limitations, this wouldn't be a problem. Any advice?

Thanks.
