Wedding dresses under $200

I'm looking for a wedding dress for my wedding in July. I'm not trying to spend over $200 because we'll be moving soon after our wedding. I was wondering if any of you ladies who live in Texas know of any good dress shops that aren't too expensive. I'm near Austin and I don't mind driving a bit too get there. I just can't seem to find any places that would fit my budget. Also I am willing to look online if anyone knows any trustworthy websites as well. Thanks!
