FAQ

Lot buying questions answered

What is a good sell-through rate for thrift hauls?

Most experienced resellers expect a 60–80% sell-through rate on general thrift hauls. High-quality curated lots (designer brands, specific niches with proven demand) can achieve 85–95%. Mixed general lots often land at 50–70%. Anything below 50% typically signals that sourcing criteria need tightening. The unsellable items need a plan — donation, bundling, or further markdown.

How do I calculate cost per item in a bulk lot?

Cost per item = total lot cost / number of items. This is your absolute floor before considering platform fees or shipping. Most resellers target buying bulk lots where cost per item is 10–20% of their expected selling price, giving enough room for platform fees, shipping, and a meaningful profit margin.

How many items do I need to sell to break even on a lot?

Break-even items = total lot cost / (price per item × (1 - platform fee rate)). This calculator handles that automatically. Knowing your break-even item count is powerful — it means you can confidently donate, discount, or bundle the remaining items once you've crossed that threshold, because everything after that point is pure profit.

Should I account for shipping costs when buying estate sale lots?

Yes — especially for heavy, bulky, or fragile lots. Include inbound shipping cost in your total lot cost. For local picks, include fuel and any paid help. These costs meaningfully raise your cost per item and break-even price. Resellers who ignore inbound shipping often wonder why their margins look worse than expected when they run the final numbers.

What is a good ROI target for bulk lot reselling?

Bulk lot resellers typically target 100–300% ROI to compensate for the time required to sort, photograph, list, pack, and ship individual items from a haul. Higher volume of work per dollar requires proportionally higher ROI. Items that can be bundled and sold as-is require less labour and can be viable at lower ROI targets.
