WANTED: Lady Roi #8268 & Bonny# 309/ #4207

Does anyone know where I can get a Lady Roi #8268 in a plus size at a decent cost? The lowest I have been quoted is $675. I know there is alot of embroidery & bead work & I am sure it is worth every penny, but I don`t have that kind of money to pay. It is from fall 2002 so, I thought it may get discontinued soon & may be on sale somewhere?? Anyone know?!
Also, my best friend is looking for a Bonny #309 in wine/ivory size 22 & the matching flowergirl dress #4207 in a 2 or 4 at a decent price. She said she has been quoted $425 for the bridal dress and $75 for the flowergirl dress. Know of anyone who beats that? Thanks!!
