Two personal stories, both of which relate to services whose prices have gone down radically over the past decade:
I used to use register.com for my domain registrations. A few years ago I switched to godaddy, despite their awful commercials, because they had the best price. After using godaddy, I found I also like their web site and domain management tools. So I decided to switch the domains that were still at register.com to godaddy. This required actually calling register.com. In an effort to keep my business, they offered to match godaddy's price. I told them that if they had offered that price in the first place I wouldn't have switched, but now it was too late.
For more than ten years, I have used intermedia.net for my domain hosting. They have a great service, a useful online knowledgebase, and when I do need support they are responsive. However, as more competitors have entered the field, they have remained the high-priced supplier. I am willing to pay something more to retain their excellent service and avoid the hassle of moving all my files and learning new procedures at another supplier. About five years ago, I was considering a switch, but they lowered their prices enough to keep me. But now, I am paying $35 a month for services I could get from highly rated companies for well under $10. So I wrote to intermedia on their customer service web form, giving them an opportunity to keep my business. No response. This may not be my highest priority, but I will be switching.
