Every empty ink cartridge sitting in your supply closet is worth real money. At Ink4Mail, we’ll pay you $1.00 in store credit for each empty HP or Kao Collins cartridge you send back to us — and if you have 50 or more empties to ship at once, we’ll cover the shipping too.
Here’s how the program works.
What we accept
We accept empty HP and Kao Collins cartridges. These are the cartridges we know inside and out, which is why we can route them through the recycling pipeline reliably.
Already-remanufactured cartridges are also welcome. They earn 50¢ each instead of the full $1 — and we inspect them on arrival, since refilled cartridges have a higher failure rate the second time around.
How the credits and shipping work
- $1.00 credit per empty HP or Kao Collins virgin cartridge — applied to your next Ink4Mail order.
- 50¢ credit per already-remanufactured cartridge — applied the same way, after inspection.
- Free return shipping when you send us 50 or more empties in a single shipment, in any mix of virgin and reman.
- Below 50 in one shipment? You’re still welcome to ship them in — just cover the shipping yourself, and the per-cartridge credit still applies.
How to send them in
- Log in to your Ink4Mail.com account at ink4mail.com/shop/account.
- Click Empty Carts at the bottom of your account screen.
- Fill out the short return form. If you’re at 50+ empties, we’ll email you a prepaid shipping label.
- Pack the empties, drop them off, and we’ll apply the credit to your next order.
No special packaging, no membership fee, no hidden steps.
Where your empties go
The empties you ship to us don’t end up in a landfill. We aggregate them and forward them to the manufacturer that produces the Colorlabs Remanufactured cartridge line, where they’re cleaned, inspected, and refilled through a 15-step process before being sold back into the market at a fraction of OEM pricing.
That’s the loop: your empties become someone else’s working cartridge, and the savings flow back through the whole supply chain — including to you, in the form of credit on your next Ink4Mail order. You can browse the finished Colorlabs lineup any time on our Recycle page or our Specials page.
