I know we can't use coupons codes from other rewards sites or from emails directly from a merchant. I see in the sticky though that we can use codes posted on a merchant's site.

My question falls into a gray area, I guess, not covered by either of the above. I received a coupon in the mail (snail mail) from 1800PetMeds. It's directly from the merchant, not a third party. It's a "we miss you" promotion. Can I use that code and still get credit from Sunshine?

(I know any credit would be on the amt. of purchase after coupon)

Thanks for any help!
