I just ordered our STD's... a little late, but oh well (5 mos till the wedding)... I got them on vistaprint. They are the big magnets, about 5 1/2" x 4 1/4". I got 80 & also got envelopes. Shipping was free. The whole thing cost $51!! (if you remember I asked (last week I think) about the caricature std's that were going to cost me $165) Great deal!
I think we also picked out our invites! Gotta get them ordered too, maybe this weekend.
