Welcome to the exciting and, in our family's case, highly addictive world of Disney pin trading. There are numerous online places where you can purchase both individual pins and starter sets before arriving at Disney World. Last time I checked, a search of "Disney pins for sale" under google.com returned over 300,000 results. Some of the places I like are
www.disneyshopping.com and
www.laughingplacestore.com. Ebay also features an entire category with a large selection of Disney pins (type Disney pins into the search field).
If you would like to surprise someone with the pins upon arrival to your Disney resort, then you may want to visit
www.memoriesbybetsy.com. This is a company, local to the WDW area, who will create specialized gift baskets that can be delivered right to your resort. Simply pick what you would like in the basket and they will do all of the work.
We love to purchase extra pins before our trip so we are ready to go when we arrive at the parks-wouldn't want to miss any trading opportunities. Happy trading!
