I haven't seen anything at a camping world that I couldn't get elsewhere - so apparently they aren't doing the "sole source" business model very well.
With all due respect to the Good Same Care Team (who are just doing their job the way they are allowed), complaints like this don't really benefit from the "talk to us privately" response. It ends up looking like Good Sam is going to give the "complainer" a private adjustment to their purchase while letting the rest of us infer that we will be paying more by shopping at CW.
