We received the service for 3 months when we bought our new car in mid-February, so they called DH in late May to let him know the trial period was expiring, and gave him several options, but none were as good as these deals, which he told them, but they wouldn't match these prices, so he let it expire.
Sure enough, they called last week and offered 6 months for $28.11 including taxes and fees, and I made sure to get them to say on their recorded line that they would not be storing our credit card information, and they were only authorized to charge this one purchase for this six month period and absolutely no automatic renewals, and their rep said, no, of course we would not do that.
we'll see.....
