Policy change, or blacklisted? (Re: Membership)

Lidio thought this was worth mentioning said

Is Casemates no longer included in a monthly Meh / MorningSave / SideDeal membership? I notice there is no longer an option to sign-up through the Casemates site or at checkout.

Because of the insufferable direct-shipping restrictions in my state (Rhode Island) I was an on-again, off-again subscriber – but after my most recent “one-click” cancellation, I noticed I couldn’t resubscribe without going through another Checkout.org affiliate.

Has anyone else encountered this?
