I just got through shipping out a quilt kit to our lucky winner for the August shophop. Each shop in the hop is giving 1 prize, which is a 100 dollar shopping spree or a quilt kit worth $100. The choice of which to give is up to the shop.
The way it is supposed to work is you'll get an email from Fabshophop telling you that you've won a prize. The shop is given your name, address and email address and is supposed to contact you telling you what you need to know to redeem the prize at their shop.
The person telling you that Fabshop was supposed to give you a certificate number was incorrect. If they are giving a 100 dollar GC or shopping spree, it is up to the shop to establish the GC and advise you how to redeem it.
The person at the shop may have been confused, as in most hops the email coming from fabshophop does give you a certificate number for the prizes, which are most often worth 10 dollars. For the August hop though, the procedure is changed since the shops are giving one 100 dollar prize instead of 10 ten dollar prizes.
I would suggest you email the shop and ask her to look at the email she got from Fabshophop, which explains to the shop owner what to do.
If you don't get any satisfaction from the shop owner, contact Laurie or Mandi at Fabshophop.com and tell them about the situation, and ask their help in resolving it.
Good luck!
