I think I might cancel. I'm not watching ads and I'm not going to pay the extra $3/mo to opt out. I don't know if I'd end up paying more than the subscription cost in shipping though....
I’ve literally never streamed a single video from prime and don’t plan to. The deals for prime members and shipping alone save me more than the yearly cost. The instant their yearly cost outweighs shipping fees I’ll cancel in a second.
