I would only use this in combo with the 20% off B-day coupon so it would result in far more than 5% savings.waste of points imo, you get 20% off with a printable birthday coupon from this thread, 8k points for 5% more is hardly worth it

it expires 10/31 and is usable multiple times no problem, and even stacks with certain other coupons/offers.
i dont think you'll ever really want to stack a birthday coupon with B2G1
I stacked the B2G1 with the B-day coupon and it worked last week. You may be able to stack the two coupons but be sure that the two coupons don't discount the same amount (ex. 25% takes off 10 and you have a $10 PUR coupon).Can someone confirm if birthday and this coupon stack I've got a copy of Diablo on PS4 on hold and I could get it crazy cheap if all goes well.
