Reseller Pro Tips
Restock Day Strategy
Items cost $7-12 on restock day but you get first pick. Target electronics, brand-name items, and sealed products that sell for $30+ online for the best ROI.
Dollar Day Volume Play
At $1/item, even items that sell for $5-10 on Facebook Marketplace are profitable. Focus on quantity over quality on clearance days.
The 3x Rule
Aim to sell items for at least 3x your buy price. This ensures profit after marketplace fees and shipping. Below 3x, you risk breaking even or losing money.
Local Sales = More Profit
Facebook Marketplace and local pickup sales have zero fees and zero shipping costs. For heavy or bulky items, local is almost always more profitable.
