What other RV supply stores are there in most cities? Most RV dealers have a small store but they too are often rather expensive. Simply put, CW has little competition. Most retail stores do not compete directly with online vendors. I would rarely order from CW online as there are too many other vendors far cheaper.
What CW offers is convenience. We're on the road and need something quick for our trip and CW has it including repair parts for many RV's. Any larger items we can plan for I buy elsewhere. When going to CW you're paying for the convenience of not having to shop online and wait.
