You probably clicked on the "get $10 back on this purchase" link and accepted the program. It doesn't automatically enroll you after you buy from them. SBS's website says to "Call 1-888-527-6839, M-F 8am-8pm, Sat. 8am-2pm, CST." I just checked, and Option 5 on the menu is to cancel it. Tell them you don't want it. I think the employees for SBS get paid to persuade you to keep it. Just keep saying no, and they have to disenroll you.
