I dont think that price is bad at all. But if you want to keep looking I got my dress from bestbridalprices.com and they have all designer dresses at low prices I paid $699.00 for my maggie sottero gown and it came with my veil and shoes for free up to a $120 value.
I also didnt pay any tax or shipping.
