I am sending off your envie today...This is my first envie so I hope what I send is ok. SOME have a quick expiry....but I knew I wouldn't use them and thought I would pass them on rather than just throw them out. I don't know if you can stack, but I have sent 3X$1.00 kleenex coupons with different UPC#'s that I put in there just in case.!!!

check your mail box!!!
