Remember New Coke? It was wildly unsuccessful. Fortunately, New eBay ain't half bad. Everything from the apps to the logo to the main site has been redesigned, and mostly for the better. Definitely for the more expensive.
Now, everything on eBay is heavily curated—each time you visit the site, you're going to get suggestions of products it thinks you want, based on your past searches and purchases—even if you don't know you want these things. Product pages are totally new with huge images and cleaner item information. And the company has made it a hell of a lot easier to spend money because now you can link your PayPal account and your eBay account. So when you see something you like, you can buy it with just one click, a la Amazon.
Along that same spendy theme, there's a new wishlist feature that looks like a Pinterest board. It shows you pictures of items that have been listed recently so you know when there's a vintage Rolling Stones poster or a great pair of Persol shades on the block.
It's a welcome change if you used eBay before, and might get you interested in its wares if you hadn't taken to online auctions before. Most of all, it's going to make spending your money there way, way easier; whether that's welcome or terrifying depends on your relationship with your checking account.
