Email them and tell them to upgrade you. Most companies will do it, since they don't want to lose a customer like you who can overpay for 2 years w/o complaining.
eh, some are, some aren't. for $20/month, I give you a gig of ram. (I'm out of space until I get my new server in this evening, which tells me that my prices are low)
My guess is lallysingh believes that tocomment is paying $20/month just for a RAM upgrade, and not for a full VPS that happens to have 360MB of RAM (he was unclear, but I assume he's on Linode like you). I can't think of a better deal at that cost.
I think I signed up for 360MB two years ago at the same price. Have other resources increased? Bandwidth? CPU?
Don't get the wrong idea, I love the service, and the prices are still very competitive, it just seems strange in general that prices aren't falling faster. My own VPS experience is the only concrete example I have so that's why I mention it.
2 years ago $19.95 got you 100MB RAM, 4GB disk, 50GB transfer and a slower technology/CPU. Now you get 360/12/200 with Xen and SMP -- http://tinyurl.com/7jvrx4
