Well, I believe they just stopped allowing people to stack these two coupon codes. I went to their site and tried it (I think you actually have to put the paper in the cart, then apply the coupon), but along with the info on the promotion they basically say it's not combinable with other offers.
So, I figured I'd order on the phone like everyone else here was having success with. I ordered Quake 3 (which brought me right above the $50 limit). I then told the order representative I'd like to add a few coupons on there..gave him the $25 off $50..that was fine. Then I gave him the number for the case of paper. He said something like "Sorry sir, you'd have to have a purchase of $77.45 to apply the second coupon." I said something like "so, no go on the second one, right?" heh. Dangit! I don't know how people who ordered just 40 minutes ago got in, but be glad you did Maybe I got the only order rep. who actually checked things.
So, no go for me, but $27 shipped for Quake 3 was still cheaper than I could purchase for almost anywhere else anyway. Oh well, suppose they had to catch on sometime, and just my luck they would right before I called
No go on stacking these coupons any more. At least, not for me as of 1pm 6/21
