Every RV owner pays what I call the ‘convenience tax’โan invisible $1,200+ per year in markup simply because they buy supplies at the first place they find instead of planning ahead. RV parks, truck stops, and tourist towns prey on the ‘captive audience’ mentality, charging 40-300% more for identical items you could buy elsewhere.
The worst offenders shocked me when I started tracking prices. That $8 bottle of RV toilet paper at Camping World? Available at Walmart for $2.97. Propane refills at RV parks average $4.50/gallon versus $2.10 at suburban gas stations. I watched a couple pay $47 for jumper cables at a KOA storeโthe same cables cost $12.99 at AutoZone 3 miles away. Over a year of weekend trips, these ’emergency’ purchases add up fast.
Here’s what veteran full-timers know: Amazon delivery to General Delivery works in 99% of post offices, even in small towns. Mail yourself supplies 3-5 days ahead to your destination’s zip code. I’ve shipped everything from specialty cleaning products to replacement parts this way. The post office holds packages for 30 days, and it’s completely free.
The system that saves serious money:
- Buy bulk supplies during urban stops (Costco, Walmart, Home Depot)
- Use Amazon delivery to rural post offices for specific needs
- Join Boondockers Welcome and Harvest Hostsโmembers share local shopping intel
- Download GasBuddy for propane prices, not just gasoline
This simple shift saves the average RV family $100+ per month. That’s a $1,200 annual raise for 20 minutes of planning.
