If you really need pins you can always try Listia...its like a free auction site where you use credits to bid on things (like icoke pins) ...so essentially, its free. When you sign up do all the basic things you need to do and get rewarded with 500 credits to start you off...i recently won an auction for icoke pin for 52 credits...
Anywho, just saying....if you want more info, pm me, or use the link below...
