Discounted Starbucks Gift Cards on eBay!

I buy alot of my Starbucks gift cards on eBay. I NEVER pay full price for giftcard, especially Starbucks! Their drinks are expensive so I buy discounted gift cards on eBay, transfer the amount to my registered Starbucks card so I get my stars towards FREE drinks and food. I use coupons for the drinks to stretch my dollar even further!
