A few Convention dolls are available at Angelic Dreamz (for a pretty penny--but Angelic Dreamz is a great retailer and the dolls are probably pretty limited, and the prices include shipping within the US):
Tyler the Bride $325
Sydney Chase Bridesmaid $325
Matt Wedding Groom $300
Ava Gardner Tinsel Town $275
Before you buy--I just saw a note on Tonner's blog that a few left-over items may be posted for sale on Tonner Direct later on, so keep that in mind, unless there is an item you simply must have.
