Selling Guide
Where to Sell
eBay or Facebook Marketplace. eBay is better for multi-packs to offset shipping costs; Marketplace works well for local RV owners looking for a deal.
Selling Tips
Liquid chemicals are heavy and expensive to ship; this is only a 'good flip' if purchased in bulk (5+ bottles) to sell as a lot. Use keywords like 'RV sanitation,' 'Black water tank,' and 'Marine holding tank.' Always tape the cap shut before shipping to prevent leaks.
