I was offered a discounted price of $5.99 a month for two months for AppleTV Plus [apple.com] when I tried to cancel my current subscription. Rates recently went up to $12.99, and it's just not cutting it for me to be a full-time subscriber at that price. For $5.99, I'll keep it a little longer.

This is YMMV as there's no guarantee you'll get the offer, but I imagine you've got a pretty good shot at getting it if you're a current subscriber!
