Rule of thumb: check eBay sold comps first. Few sold listings can mean limited demand or a rare item. Check the match and condition before deciding.

Listing templates
Photo checklist
Clear photos help buyers assess your item. Aim for 6–10 shots per item.
Lighting trick: shoot near a window during the day, item on a clean neutral surface (white sheet, wood floor). Never use the flash.
Workflow & reference — weekly rhythm, discount schedule, fees
Weekly rhythm
Discount schedule
If an item hasn't sold within the window, drop the price. Review demand, photos, and condition before changing your price.
| Days listed | Action | Why |
|---|---|---|
| 0–14 | Hold target price | Give buyers time to find the listing. |
| 15–30 | Drop 10%, refresh photos or title | A lower price may reach a different buyer budget. |
| 31–60 | Drop 20–25%, cross-post elsewhere | You're in stale territory. Break the pattern. |
| 60+ | Go to minimum, or bundle with similar items | Capital stuck in stale inventory is worse than a small margin. |
| 90+ | Consider bundling or donating | Storage and mental load aren't free. |
What to buy
| Buy | Why |
|---|---|
| Known brands (Le Creuset, Patagonia, Pyrex, Lego, Coach, Stanley) | Named brands have comps. Comps = confidence. |
| Items with sold comps ≥ 3× your cost | Gives margin for fees, time, returns, bad photos. |
| Small, light, shippable items | Shipping ≤ $10 keeps margins healthy. |
| Large items with local demand (furniture, lamps) | Cash + pickup on FB Marketplace = zero fees. |
Skip: fragile glass you can't ship, generic fast-fashion, items with broken or missing parts (unless Lego, by weight/lot).
Platform fees
| Platform | Type | Fee | Notes |

Fee excludes optional promoted-listing / seller-ads fees. Payment processing is bundled in for the marketplaces that charge it.
Reselling fee FAQ
Quick answers to the most common questions about platform fees and reseller profit.
What is BIDonBOT?
BIDonBOT (say it "bid on bot") is a reseller toolkit with free tools and optional Pro selling features: live eBay comps while you're sourcing, a fee calculator for every major platform, a reverse pricing planner, listing templates, and a weekly workflow. Free includes two photo scans per hour. Pro adds more scanning, AI listing drafts, and sell-ready plans.
What percentage does eBay take from a sale?
eBay charges approximately 13.6% in most US no-Store categories, plus $0.30 per order at $10 or less or $0.40 above. The fee basis includes buyer-paid shipping and applicable sales tax. Category and account rates vary.
How much does Poshmark take from a sale?
Poshmark charges a flat $2.95 fee on sales under $15, and 20% on all sales $15 and over. Buyers pay for shipping via a prepaid label Poshmark provides.
What are Mercari's selling fees?
Mercari charges a 10% seller fee on the item price plus buyer-paid shipping, with no separate payment-processing fee.
Does Facebook Marketplace charge fees?
Local pickup on Facebook Marketplace is completely free. This calculator covers local pickup; verify any shipping fees in your seller account.
How do I calculate my reselling profit?
Net profit = Sale price − Platform fees − Shipping cost − Item cost. Selling a $75 item on Poshmark with an $8 cost: $75 − $15 (20% fee) − $0 shipping − $8 = $52 net profit, a 650% ROI.
What items are best to resell for profit?
Prioritize known brands (Le Creuset, Patagonia, Pyrex, Lego, Coach, Stanley) with eBay sold comps showing at least 3× your purchase price. Small, light items keep shipping under $10. Large furniture works as free local cash sales on Facebook Marketplace.
When should I discount a resale item that isn't selling?
Hold your price for 14 days. Drop 10% at day 15–30, 20–25% at day 31–60, and go to your minimum or bundle after 60 days. After 90 days, consider bundling or donating — stale inventory and storage costs aren't free.
