How ThriftBot Prices, Researches, and Recommends

ThriftBot is a decision engine for resellers: it focuses on net profit and risk reduction — not hype pricing. Here’s the logic we use.

1) Category screening

High-ROI (preferred)

  • Tested electronics (complete)
  • Gaming consoles & accessories
  • Branded footwear & sneakers
  • Small kitchen appliances (working)
  • Vintage / collectibles
  • Brand-name tools

Medium-ROI (case-by-case)

  • Clothing (brand + condition)
  • Books/media (demand-dependent)
  • Toys (brand + completeness)

Low-ROI (avoid)

  • Printers (returns)
  • Very heavy, low-value items
  • No-name electronics
  • Missing critical parts

2) Condition & completeness

Standard condition language

GradeMeaning
NewNever used, original packaging
Like NewMinimal signs of use
Very GoodLight wear, fully functional
GoodVisible wear, functional
AcceptableHeavy wear but working
Parts/RepairNot fully functional

Instant red flags

  • No way to test
  • Water damage / corrosion
  • Cracked screens or broken ports
  • Strong smoke smell
  • Vague seller descriptions
If risk exists, the price must compensate — otherwise we pass or negotiate lower.

3) Platform-aware pricing

We price by platform

  • eBay: broad demand, higher fees, great for tested electronics & collectibles
  • Mercari: simpler, lower fees, solid for mid-priced items
  • Facebook Marketplace: best for local pickup and bulky/heavy items
  • Poshmark: high fees, only worth it for specific apparel brands

Conservative fee defaults

  • eBay: ~13% total
  • Mercari: ~10% total
  • Facebook local: 0%
  • Poshmark: 20%
We prefer ranges over single numbers: low-end = fast sale; high-end = patient sale.

4) Shipping estimation

USPS Ground Advantage

Best for most items 1–15 lb (small electronics, accessories).

USPS Priority

Useful for lighter items needing speed. Flat Rate only when it wins.

UPS / FedEx Ground

Often cheaper for bulky boxes or heavier items (5–40 lb).

Dimensional weight can crush profit. If shipping can’t be estimated confidently, the deal gets downgraded or rejected.

5) Profit calculation

Net Profit = Sale price − (platform fees + shipping + packaging + cost of goods)

  • Target 2–3× return on cost when possible
  • Thin margins require high velocity
  • Uncertainty → we publish a low–high profit range

6) The recommendation

Every output ends with a clear decision and a plan:

  • Buy price (max)
  • Sell range
  • Fees + shipping range
  • Net profit range
  • Best platform
  • Risks to check
  • Go / No-Go
