The phenomenon of mystery packages and undeliverable packages (NPAI - "N'habite Pas à l'Adresse Indiquée" meaning "Does Not Live at the Indicated Address") is exploding in France. Between viral unboxing videos on TikTok and resale opportunities on Vinted or eBay, buying lost packages by the kilo has become the best way to unearth treasures at a lower cost.
However, with this craze, many websites have emerged, and not all are created equal. Between disguised clearance sales, pre-sorted packages, and hidden shipping costs, it can sometimes be difficult to navigate.
In this article, we offer an objective comparison to help you choose the best supplier of lost packages and optimize your investment.
What is a real undeliverable package (NPAI) or logistics return?
A true lost package is a package that could never be delivered to its final recipient (address error, NPAI, unclaimed package at a relay point) or a raw customer return from large platforms like Amazon.
The anti-waste law prohibits the destruction of these products, so they are bought back by specialized companies directly from logistics providers and then resold by weight.
The problem? Some sites capitalize on the trend and sell "mystery packages" that are actually end-of-series low-priced Asian products or outdated clothing from bankrupt stores. This is classic clearance, not lost packages!
The number 1 trap: Pre-sorting packages
The biggest fear of a buyer of packages by the kilo is to end up with a box filled only with worthless phone cases or USB cables.
Why does this happen? Because many platforms sort shipments. They discreetly open packages, retrieve high-value items (smartphones, consoles, designer clothing) to resell them individually on second-hand apps, and put the rest by the kilo for the general public.
At ColisNPAI (Lost and Found), we made a radical choice: our business is solely wholesale by the kilo. We do not have any resale accounts on platforms to guarantee total transparency to our buyers.

How to maximize your gains by buying lost packages?
If your goal is to generate additional income by reselling the contents of your mystery packages, here are our 3 professional tips:
-
Aim for intermediate formats (10kg and more): Buying 2 or 3 kg limits your chances of hitting a jackpot. The 10 kg format is the ideal compromise (our best-seller) for diversifying content.
-
Use the right resale channels: Take beautiful, well-lit photos and resell clothes on Vinted, high-tech items on Leboncoin or eBay, and unusual items in unboxing videos on TikTok to attract buyers.
-
Calculate your cost price: By taking advantage of free delivery for orders of 10kg or more, you reduce your purchasing logistics costs to zero, which directly increases your net resale margin.
