Say yes to the dress!

So I've been obsessively watching Say Yes To The Dress on TLC... Am I the only one that thinks some of their budgets are crazy? But then again I know I'm planning a wedding on a low budget. 
The brides seem to have such awesome experiences when shopping there, seems more special in a bridal boutique and if you have a budget of more than 2k. 
What about wedding dress shopping experiences if your budget is only a few hundred? How is it shopping at retailers like David's Bridal?
