Went to the site to check on the status of the giveaway--it's now closed. Reebok has finally given away their million dollars worth of shoes (I thought it would have happened much sooner!)
I hope everyone who was double charged can get it taken care of quickly. I'm sure they are working on the glitch. Was it a certain card it was happening to? My debit card wasn't even charged till the 3rd (I was getting worried my transaction wasn't going through!), and it was thankfully only charged once.
Anyway, good luck to all who ordered on receiving their correct size!
