I agree with Gary..never forget about your database....do mailers often.
I just ordered some postacrds from Vistaprint.com they have nice cards very reasonable and you design them . I use the (thank you cards~ modified) for Birthday cards. Just customize them. Type what you like.
I get my VIP cards-- Lotion Bonus cards, labels for my lotions gift
bags and bottles, referal cards and Business cards there too.
Last time I tried the linen finishon my postcard inactive In house malier ... I like the glossy better. They were nice but the full color glossy is my fav. JMHO
