We adjusted prices when we switched a new reseller and changed the packages so they gave more space and bandwidth for new customers. We grandfathered in existing customers with the original packages and prices. It's nice to make loyal customers feel loved.

In last 10 years never changed our plan & price. Though we are planning for a major overhaul soon.

Well, there's no doubt in my mind that many of the advanced servers selling today will become the lower level servers of tomorrow. The prices may not vary much, but what is offered at that price point must certainly change.

Already adjusted few times. Market is changing so need to change prices and services as well. But this is good. Such a process improves quality of offered services.

We did slightly change our pricing once but also changed our plan details and features, without changing anything to already established customers, of course.

I haven't adjusted my prices yet, but am working on balancing my services between my different plans.

I'm just hoping I can get things set for people to really want to use my service.

Well i only adjust my prices if my competitives have low prices.

Twice due to addition to new servers.

From my point of view, choosing the right price for a product depend on the market it is related to.
It might not be a good idea to change prices frequently. This article might help as well
