Need Suggestions - Bridesmaid Dress Shopping on Saturday

I'm going bridesmaid dress shopping with my girls on Saturday. I'm only having 3 - one maid of honor and 2 maids so hopefully things should be simpler.

We're going to Macy's Bridal in Smithaven which is where I purchased my wedding gown. They're having a 15% off sale on bridesmaid dresses (not sure if this is only if you purchased your gown there, but it's worth checking on if anyone is interested.)

Anyway, I haven't made any appointments elsewhere yet. Any suggestions? We're coming from the Stony Brook area. I'm kind of hoping they find something at Macy's because it'll make things a bit easier if they get their dresses from the same place, but I want to be a flexible bride and let them choose their own dress. (I'll pick the fabric/color.)

So basically, I'm looking for any suggestions on other places to check out with them and any hints/tips from those of you who've already gone through this!

Thanks!
