I hope no one thinks that RV dealer stores or even Camping World come close to Walmart pricing. I have found dealer stores and Camping World mark up is close to 300% on some items. Walmart is a lot less because they sell on volume. Check prices on RV lubes and RV toilet chemicals - big discrepancy their, too.
