Does anyone know if dodressme.com is a reputable site for buying a wedding dress?

I found the perfect wedding dress this weekend but it's $800 over my budget (and I was hoping to stay below!). My mom has said she'd pay the difference but before I spend the money I wanted to make sure I could do better somewhere else. I looked online and found the dress on dodressme.com for $269. The website looks legit but I cannot in good faith order my dress from a website unless I know that it's reputable. Has anyone heard of this site or used this site before? It seems too good to be true but if it isn't, then I have to order my dress there!
