BM Dress situation Q re: ordering HELP

I'm finally going to order the girls' dresses shortly as both my bm are no longer pregnant. 3 of my bm are FH's cousins (we're very close)...ALL of them are leery about ordering the dresses from gownfind as they are not very computer savvy and are hesitant. They've all dealt w/ salon 'A' for their weddings & that is where we were going to go to try on the dresses (& then order thru gownfind---she has a location, but does NOT have the dress to try on).

A few things.....

1) If they want to order thru Salon A & buck up the extra 80. should I just let them?

2) My MOH & other bm (who is out of state) want to order thru gownfind (should I let them)
Will color lots REALLY be that different?

I'm also hesitant b/c Salon A & gownfind are about an hour apart & just getting them all together is going to be a project once, let alone twice.

Thanks ladies.

Well some girls were going to order from one salon and 2 others from another.....
