My daughter (8) started collecting pins this trip.
We bought the lanyard with 4 pins, 2 to keep, with duplicates to trade. I thought it was a good start.
Then i bought a hat, with 6 pins, at AK. I wanted the hat, and we struck a deal, for the pins. I gave her a deal. 6 pins for $12.00.
It was a lot of fun for her. I had to bite my tongue more than a couple of times, though. She would trade, sometimes just for the sake of trading. Gave up some pins that she later regretted. I just finally realized that she would trade for the ones she liked, but not so much for the value.
The cast members will trade, and you can also trade from the books at the pin carts.
Most of the pins, are 6.50, as turnlisa said. Some are more, and you can customize some, which can be alot. We did a couple of these, and we made sure she knew, not to trade.
I wish I had thought that she would get into it. I would have tried to be prepared, with some pins to trade, that didn't cost alot. I didn't even realize that the
Disney store carried them.
My daughter had her spending $$, and used quite a bit of it towards pins. We came home with 25 of them. But it was worth it---It is her favorite thing from the trip.
Have fun.
