If you’ve purchased a new computer, tablet, smart phone, TV, or any other electronics recently, there’s a good chance you had the chance to save money on a refurbished version. You’ve also probably wondered what, exactly, does “refurbished” mean? And whether it’s worth the risk

Surprisingly, refurbished doesn’t necessarily mean an item is used or repaired. Some refurbished items are classified as such simply because their outer packaging is damaged or opened. Refurbished can also mean an item was sold and returned, but not used. Floor models and trade show demos can also be classified as refurbished. In fact, only a small percentage of refurbished electronics have been through a repair process. Here are five tips to help you save when buying refurbished electronics.

Buy from a Reputable Source

It’s a much better bet to buy refurbished electronics from established retailers or manufacturers versus a local repair shop. Retailers such as Best Buy use certified technicians to repair and inspect all refurbished items. Apple has a section on their site dedicated solely to offering refurbished products.       

Know the Return Policy

The return policy on refurbished products varies widely. Some retailers or manufacturers may not even allow returns (if that’s the case, don’t buy). Look for at least a two-week return policy, which will be enough time to know if your new gadget is working as promised. On a related note, avoid products marked “as is.” That could be a signal a product has known issues that haven’t been repaired.

Research Your Purchase Protection

Buying refurbished electronics with a credit card that offers purchase protection may (or may not) provide a second line of defense if something goes wrong. Some purchase protection plans exclude used products, so be sure to know what your card’s parameters are before you buy.

Maximize the Warranty

Warranty periods can vary widely, depending on where you purchase. Big box retailers may only offer a 60- or 90-day warranty, whereas manufacturers will usually provide a longer warranty. Remember to ask about the warranty period. If there is no warranty at all, it’s better to buy elsewhere.

Check for Accessories

Refurbished electronics need accessories, too. Be sure to confirm that your purchase includes all chargers, cords, adapters and accessories in good working order. Also remember to ask for the the correct owner’s manual and any other original paperwork.
