Printing Invites Cost?

Does anyone know what it will cost to thermographically print invites if you supply the paper? (Raised letterings (not letterpressed).)

I'm wondering if it's not cheaper just to buy a cheap nu art invite and adorn it after the whole set is printed, instead of buying envelopes, paper, etc. separately and not having the color match!

check out ac moore & michaels they have sets of invites you print for like $25 & also have coupons for 40% off...
walmart actually has them too for $25 too. Shop around to get a good price on the ink cart. & i think it will be better & cheaper than doin it seperatly...good luck
