A better buying ritual
From “looks cheap” to “I know why this works.”
Nettlemark gives each candidate a visible decision trail, so your best flips are repeatable and your bad buys are easier to spot before cash is tied up.
Start with the buy
Enter source cost, model, storage, condition, and what you already know about the unit.
Compare the exits
See expected sale prices across Amazon Renewed, Swappa, and eBay after fees, shipping, and channel fit.
Ship with confidence
Protect the margin with IMEI checks, honest grading, accurate listings, returns, and warranty exposure in view.

The best channel is not always the highest sticker price. It is the cleanest route from this unit to cash in hand.
Make the margin make sense.
Tell us what you flip, where you source, and where the math gets murky. We are building Nettlemark for the people who know the difference between revenue and a real return.
