Hi. Good idea to start when 4th quarter is on the horizon!
Ebay will send you a discount code in your email on or shortly after October 1. You can then pick out your supplies and enter the code during checkout.
If you don't get it within the first week of October call customer Service. There was a gliche when I started my store. I didn't know and never got the code. When I finally got things sorted out the gliche kept happening.
