Forgive my tangent, but do you have any idea why you like to write it as "CostCo"?
I notice it's a common practice on news.y to find (or invent) sub-words in names and capitalize them. Like I remember everyone writing "GroupOn" for the portmanteau of "group coupon"
It's puzzling to me and I want to understand where you're coming from!
I assume that's instinctive camelCase[1] and/or exposure to a very large number of software packages and startups that do go for the ransom note look in their branding.
While I like the other responses better, at one time it was part of their branding. From a phonological standpoint, it was perhaps an effort to guide the pronunciation of the name as "Cost Cō". I tend to type it that way because I hear it that way.
