Amazon Prime members: If the annual Prime cost went up, what's the max you would pay before you'd decide it's no longer cost effective for you?

Amazon Prime – free 2 day shipping on most Amazon items, plus movie and TV streaming, for $79 per year. The cost is going up, when and how much is not yet decided by the Amazon big shots.

To me, $79 is a good deal and I pay it willingly. Any more, though and I would cancel and revert to just waiting till the cost of my items is $25 and I would get free shipping (but not 2 day shipping). I don’t use the streaming videos. Amazon would still get my business, but not my $79 per year, and I would probably not buy as much from them, because if I needed something quickly, Amazon would not be the best bet. Right now, if I need something, it’s very easy to check Amazon and know that in two days, it’s delivered right to my door.

I sent a “contact us” message to Amazon and told them I was not supportive of a price increase. They sent back a message stating they are considering a price increase but are not yet sure how much.

What’s the max you would pay for Prime before it would no longer be cost effective for you?
