I have two auctions for the coke caps, two auctions for the Powerade caps. Since My Coke Rewards sometimes gives you promotions for entering certain caps. I make my auctions cap specific, thus making them different auctions between say my Powerade Caps and my Coke Caps. Hence if I list more than 2 of either it stops me. But it lets me do it this way..
You're going to have to show me that part.... I see it says I cannot have very similar items BUT under "exceptions" it states: "Discount or Promo Codes Exceptions: unique one-time use codes and certain rewards points"
Every one of my codes are unique one-time use codes.
