I found the trick is (a) sing up on line and if you are like me - you have more than one email address - they have bar codes on them - so you can get double without double numbers (2) print more than one copy out - if you don't have enough with different numbers - go for a second transaction; their computer does NOT save the numbers from one transaction to the next - which is why they right VOID on the ones you use (c) join their VIP club or AQS and get 10% off - this doesn't work on everything and you can't get more than 50% off anything - but it brings those 40% coupons off. BUT MAKE SURE - you don't handd over yourt 10% card until the very end - the computer will take the 10% off whatever is applicable. I RARELY pay full price for anything - but I get what I want - and buy it if I think I may want it - when I can - I have a fabric piggy bank and I add to it with every pay check !
