In most countries I can think of including my own, prices are usually done with the currency symbol first, then the price like "£12.34" or "$98.76". I seem to imagine somewhere I went as a child I saw it suffixed instead, like "12.34£" but I can't remember where.
How common are prefixing and suffixing in relation to each other? And in countries which use the "minority" system, how rigorously is this adhered to? I imagine street vendors with handwritten signs would use the one most common in that country, but what about big businesses dealing with international companies? Do they change to use the more "common" one?
