There's also the $15 off $150.... just 5 bucks less discount than with the discover 10%.
Also, I doubt it'd work because they say it wont, but I was able to add the discover 10% and the $15 off $150 to my cart. But like I said, it states pretty plainly one coupon per customer and each coupon is not good with any other coupons.
I'd get this if I didn't have to pay the CA sales tax... adds $16 bucks to the deal for me.
Edit: They catch the double coupon use when you go to checkout.
Total for me shipped to CA is $201.68 less $20 comes to $181.68.... I can't resist... my wife is gonna murder me.
