That's it, Disney wins again. After reading reports on the Marathon Weekend expo I broke down and bought the Runner Bundle for the half despite only wanting the magnet. Ideally, I would get the challenge magnet too, but I'm not willing to shell out for more pins.
I've collected one from every runDisney event I've completed, although I almost missed out on Wine and Dine if not for returned magnets at Merchandise after the half marathon. I would be stressed about it all weekend if I couldn't find one at the expo and I'll be ...er... DONALDED if I give any of those ebay vultures any of my money.
On that note, if anyone wants those pins in April for MSRP, I'll be willing to part with them.
