I just wanted to share that I have found a really great website for inexpensive robes (waffle, satin, and more). It was a life saver for me and I never saw anyone talking about it. I haven't gotten my order in yet, but I ordered them yesterday and they have already shipped! I got them on the Black Friday sale which made them even cheaper. ($7.99 satin robes!) It's too late for that sale now, but their Cyber Monday sale is great too, it's $10.99 Waffle Robes!
Check this site out if you are looking for inexpensive robes for your bridal party. http://robemart.com/
Hope this helps someone out there!
