anyways if it is an electronic coupon (you got it from apple.com) then it is likely only for online. not that a ten dollar coupon is worth anything when you are buying 2000 + dollar computers
If that's the survey you are talking about the coupon is only good at a Physical Apple Retail Store not the online store. The Coupon is actually pretty good as you only need to spend $100 to get te $10 off and in theory you can take the survey more than once to get more coupons. Only one per visit though.
