Does anyone forget what pins they have and trade for or buy double of the same pin? I'm in Louisiana so I have today off from school because it's Mardi Gras. I thought I'd go through my pins to organize them and to clean up my PinPics account. As I'm going through my pins, I realize I have double of a few of them. Now this was not me buying two of a pin with the intention to trade it or doubles from a mystery box. For example, I just traded for the Patriotic Tiana pin last week and it arrived yesterday. I was so happy and showed it to my sister. I went to put it in my PatF box and realized I already own it. I guess I have more traders now. I'm bored and curious. Does this happen to anyone else?
