Unfortunately, I have run into problems with these free PiZero with a subscription from IMS.
The first time, the offer was a free original PiZero with a 1-year subscription. Paid for the subscription, got the invoice showing the free PiZero, but the package was empty. A call to complain got me an explanation about "some packaging problems" but I never got the PiZero.
This week, another e-mail from IMS offered the 3 items mentioned above with a subscription renewal. Doing the renewal from their web site using the link in the offer email, never showed the 3 free items in the offer. So I did not hit submit for the order.
IMS appears to be a distant "third party" with respect to offers of Rasberry Pi hardware. Beware.
