How to spot underpriced electronics on Craigslist, OfferUp, and eBay
Craigslist and OfferUp are where you can look at the item. eBay is where returns and shipped comps are easier to read. Underpriced still means a lower live asking price for the same spec, on whichever of those sites posted it.

Specs to match across Craigslist, OfferUp, and eBay
Start from the model guide so the chip and storage are fixed, then look at all three sites. A cheap post that hides the capacity is not a find.
Storage tiers
Write the capacity into your search. The same model name with two storage sizes is two products.
Condition checklist
Match the model, the capacity, and the working condition before you call a listing cheap.
- Craigslist: local, usually cash, free to post in most for-sale categories.
- OfferUp: local or shipped. Shipped sales add a service fee.
- eBay: shipped electronics with a stated return window. Fees sit with the seller.
- Do not leave the site that hosts the listing to pay.
Marketplace fee breakdown
Seller fees for electronics you might flip are not the buyer's price and not a sold average. The ranges below are the same qualitative notes BuyLow publishes on its reselling guides. The marketplace fee page is the source of truth, because rates change.
- eBay: About 13–15% final value fee on most categories plus a small per-order fee; lower for some electronics. Fee page: https://www.ebay.com/help/selling/fees-credits-invoices/selling-fees?id=4822.
- Mercari: A selling fee of about 10% plus card processing; check the current rate. Fee page: https://www.mercari.com/us/help_center/.
- Facebook Marketplace: Free for local pickup; shipped orders pay a percentage selling fee. Fee page: https://www.facebook.com/help/marketplace.
- OfferUp: Free for local sales; shipped sales pay a percentage service fee with a minimum. Fee page: https://help.offerup.com/.
- Craigslist: Free in most for-sale categories; some categories charge a small posting fee. Fee page: https://www.craigslist.org/about/help/posting_fees.
