I recently did the upgrade deal to the MM Premium (giving 4, $15 coupons), but am unable to redeem any of the coupons because the soundpools I'm wanting are "on sale" (note that the product page showing what you get with the "bundle" says nothing about limits on the coupons in the first place...).

Any ideas of what to do, or how long the sales will last? I don't want my coupons to expire.
