...Stuff like that has been going on since the dawn of time. Quietly jack the price up, then immediately claim SALE, SALE, and bring the price back down to original price. Sales go through the roof, people think they're getting such a great deal, when in reality they're paying the full, regular price (or in this case with CW, you're actually paying more than the regular price, haha).
When I was in college many, many years ago (back in the early 90s), I worked for an auto parts company that was notorious for this. They would quietly raise their price on car batteries (12V), then immediately come out with big sale ads claiming big discounts on batteries, listing them at their original, regular price. They sold tons and tons of batteries this way. I installed zillions of those batteries for customers, would over-hear them rant and rant about how happy they were for the GREAT deal they got on a new battery. Didn't have the heart to tell them, they were actually paying the full, regular price. :)
Does not surprise me at all, that Camping World is using similar tactics.
