To the OP
If you were offered this at a store, depending on what the costs were to you and depending on what you had to do to secure a spot at the store....it would be a killer deal.
I suspect that you might not be getting the full story. Davids is doing what bella tried to do and a few other corporate wedding vendors have tried to do. They are getting people to work for them for $3-400.00 and cover a wedding while marketing it to the brides for $900.00. This has been tried all over the place. I was also approached and it turned out to be what i just stated. I suspect you have not been told the entire story. Davids bridal is exclusive to no one but Davids bridal and their bottom line. Our weddingday.com, martha stewart and a couple of other chains all market with davids bridal.They sell these bridal lists like hot cakes to all the vendors.
And they do not work very well at all. The girls are bombarded with E-mails and they are at the point where they automatically hit the delete button w/o even opening the e-mails. I would tread carefully and find out additional information.
But if you can get set up inside a store as an exclusive vendor... you are set big time. Doubt that will happen with Davids bridal.
