I received a box today as well. Most of the free stuff, and one of the paid items ($2.89 Packing Tape).
This is after both manually submitting a request for cancellation (I didn't want the whole hassle) and receiving their standard "could not be processed due to invalid coupon usage. You have not been charged for this order." .
I also have another email from them, less than hour after the standard cancellation email, saying one of the free items has shipped (none of the ones that came already) with a tracking number.
I hope they don't charge me in the end!
