If you haven't jumped on the RueLaLa bandwagon yet, now is the time! Through 4/25, all new members receive $20 credit when they join RueLaLa. With the great deals that RueLaLa offers, there's a great possibility that you could get things for free or cheap! The credit expires on 5/25, so you have a month to use it.
If you don't know what it is, RueLaLa is a daily deal site that has boutiques of designer items. They even occasionally have wedding boutiques which have great deals on wedding dresses as well as other items.
This post has my affiliate link in it. I receive $10 credit to RueLaLa whenever someone I referred makes a purchase.
