I had pledged 17 to either get one of the pins from this campaign and one from a previous campaign or one from this campaign and use the rest to cover shipping. For my extra add on funds it forced me to choose a second pin from this campaign only. Then it took me to a page where I would have to pay more for one of the other pins. So I backed up to see if I could use it on shipping, no luck it forced me to pick the pin. So, I skipped getting the second pin I actually wanted and grabbed a design a friend would like and then had to spend more money on shipping. Not the worst situation, just not what I was expecting and pledging for.
