Single-campaign printed maps on vinyl aren't common, because you can only use them for that one campaign. They're only ever going to be useful for those specific maps. Much more common is to buy a battlemat--a blank grid, usually with 1" squares on one side and hexes on the other--and draw the outlines of the maps as you go. Battlemats come in both vinyl and really heavy-grade coated paper. They're versatile, because you can just draw whatever map you want when and if you need it. (You don't need to be a good artist. I couldn't draw my way out of a paper bag if my life depended on it. You just need to get the idea across.)
