I realize this is an old forum, but it would be nice to have a check box that allows one to filter out products where coupons are void.  The red coupon icon is nice, but if Renderosity would like us to use those coupons (and the end result would be more purchases), a check box along with all the others that is simple...

[  ] Show Coupon Eligible Items Only

Of course, the other alternative would be to simply make coupons available on the total purchase - regardless of the item.  :)

P.S.  DAZ is WORSE.   I got a $5 off coupon, and EVERYTHING I'd add to my cart from my wish list the coupon was void.
