'get a quote' or 'get a quotation'
Quote or quotation is the same thing... I work in purchasing and generally request a "quote" (RFQ)
I have never heard anyone ask for a "quotation" on a product or service here in America. Things may be different over the pond, but here you usually just ask for a "quote." A "quotation" is usually something for which you would consult Bartlett's (a book of famous people's words), not your insurance company (for a price estimate on a policy).
I've never heard "quotation" used in this context in the States, but in Australia, I have seen/heard both "quote" and "quotation". Therefore, I assume that "quotation" is a British thing, but everyone should understand "quote" because most accounting software that generates these things is written in American English.
