Select Pin Back Style at Checkout
It would be nice to be able to attach the pin backs myself, so I can have the placement where I want. Then there could be an upsell option for people who wanted to have Stickermule attach them backs for them, this could be a selection at checkout. And the pin back preference of metal clasp vs rubber clasp is pretty much 50/50. It would be nice to be able to select the style at checkout we want also.
