Every time they try to bump me up to a higher plan I tell them that I don't need it any more and it's too expensive and they give me stupid deals. I think currently I'm paying $25 a month but they refunded me the first month where I accidentally lapsed back onto the "real" pricing, and gave me the next four months for free. So basically $175 for the year. I'll probably cancel it next time it comes up though, I basically only use it for complicated PDF stuff, and I'm sure I can find something else to do that.
You just tell them that you don't find it valuable and if you've been a customer for long enough they will bend over backwards to keep you. I used to buy several copies of CS3 and CS4 back when they came on DVD and I'm still using the same account, and moved to subscriptions with three seats as soon as they came in. So my LTV is probably fairly compared to a normal "consumer" account where they've only ever subscribed. Obviously compared to an enterprise account it's nothing, but if you're buying enterprise licensing I imagine you're getting it for less than $30 per seat per month.
I'm grandfathered in with a 30$ a month deal. I rarely use Photoshop/Lightroom and the PDF editor.
If I had to pay the full 60$ a month I'd cancel.
