Hi Courtney & welcome to the forums!
I can tell you from my perspective the Cupcake Courier is the best product out there for this purpose, I absolutely LOVE that thing! I was lucky enough to find it on sale, but I would seriously pay full price for it, it is wonderful and making cc's for my sons class was never so stress free
They do carry it at Bed Bath and Beyond and sometimes Target, but at BB&B you can use one of the 20% off coupons that come out almost weekely.
There have been lots of talks about this, if you do a search, but here is a link to one of the most recent discussions,
Hope to see you around the forums lots! Andrea
