I tried your link, it did not work. There are two pins on ebay, they both are Pi Phi pins. However, they are the pins we get upon intitiation and the asking price is only $5 less then a brand new one.
If your friend is a member of pi phi she should have the exact pin that is on ebay. If you would like to get a pin for your friend, you can go to:
http://www.pibetaphi.org/market/mktfram.htm. We have a pin for just $20 more that has a nice raised pearl.
Why would you get hate mail, if you are buying it for your Pi Phi friend?
