Need Comments on David's Bridal

(Thanks Michele) Just visited David's Bridal, and was very pleased with the attention I received. The girls were extremely nice and patient, and I actually enjoyed the experience. I wondered if any of you have dealt with them and bought a wedding gown from them. They are so much less expensive, I wondered if the service (once a dress is ordered and needs alterations) is as good as when I was there just looking and trying on. Anyone care to share? Also, how on earth do you pick a florist and a printer for invitations? Thanks.
