How to make sure you’re buying legitimate ink

One way to validate HP ink in particular is through its website. Another common piece of advice is to buy through a legitimate retailer — but that’s what the listener who reached out to Kim did, and she still got in trouble. If you want to go the extra mile, you can buy ink straight from the manufacturer’s website or in person at an office supply store you trust to avoid any potential third-party tampering. Also, make sure you’re buying from a retailer that offers replacements or returns. Also, when it comes to ink, don’t let it sit too long. Make sure it works when you receive it. Fake cartridges can be dangerous. They may leak and damage the inside of your machine. One way to watch out for fakes is by looking at the price tag.

Here’s an easy way to save money on ink

Having your own personal printer is so convenient. You can print coupons, the kids’ homework and important documents for work, all from the comfort of your home. The downside? Expensive ink cartridges — unless you purchase an Epson EcoTank printer. Kim has recommended Epson’s EcoTank printers to countless friends, listeners and readers. Why? They come with a ridiculous amount of ink right in the box — enough to print a whopping 6,000 color pages. When that runs out, you just refill the ink tanks instead of wasting money on ink cartridges. Check out Epson EcoTank printers at a Best Buy, OfficeMax or Office Depot near you, or shop online at Epson.com/EcoTankKim.
