New studies show more than 61% of us are buying second-hand stuff online. And while it saves us money and it helps save the environment, you need to be sure you’re getting what you pay for. Below are tips from shopping experts:Check the seller profile: Have they sold other things recently? What are the reviews like from other buyers? Just taking a look at their profile will give you insight on the experience you’re about to have.Ask for more: Before you agree to the purchase, ask the seller for more. Ask more questions about what you’re buying; like what the measurements are, when the item was originally bought and from where, are there imperfections, etc. You should also ask about the conditions of the home, like if it’s smoke and pet-free. Ask for pictures of all sides of it as well.How to pay: Paying by credit card is best but PayPal is another good option because it lets you dispute charges if there’s a problem.Baby gear: Check to see if the make and model has been recalled. Type it into the Consumer Product Safety Commission’s Recall website to make sure it’s still safe. Electronics: This one is tough. You really shouldn’t buy these from private sellers because you can’t guarantee they’re in full working order. Instead, try a refurbished one from a manufacturer or store. Places like Best Buy and Apple will give you a deal and still give you a warranty and tech support. Clothing: If you don’t want to buy secondhand clothing on sites like Craigslist or Facebook Marketplace, retailers are getting into it now. From Nike to Levi, they call them re-commerce programs. LuluLemon’s “Like New” and Patagonia’s “Worn Wear” programs let you get store credit for gently used stuff. The clothing reseller thredUP is partnering with Macy’s to create secondhand sections in select locations as well.
