Go to your account and you should see an active PClub membership and the date that it will end. That will let you know if you have an active account first. vouchers are only usable the month they are issued, they cannot be built up for add $5+$5 etc. it's a once a month shot. The Vouchers are applyed just before the actual purchase and you will see in the report of your cost a line item that says voucher applied -5.00 or something to that effect. It threw me when that hit also, but they did work. I'm an annual original PClub member so I do not know about the monthly or new. I have experienced hickups and oddities but it's usually associated with a new web update or changes to the Daz Site. I generally wait a day or two after things come out so they have time to fix any weirdness going on. Call the 800 Daz line if you can I've had great experience with talking to humans at Daz and things have gotten done n fixed quickly. Email has worked also, but recently they have been so swamped that the 800 line has been better. hope you get it worked out, I'm sure Daz will take care of you, they have great support.
