According to a recent research survey, 79% of shoppers have made an online purchase.

In-person shopping can be a smart way to ensure you’re getting what you pay for, negotiate better deals by haggling and avoid hefty shipping charges, but online shopping also has its perks too. You can save money by shopping online because it’s easy to compare prices at several retailers and read reviews to find the best deals. Of course, it all depends on what you’re buying.

Certain items just make more sense to buy online—either due to significant cost savings or pure convenience. E-commerce businesses have less overhead so they can sell many items for less; on average, you can expect to save about 20%. Certain items can be found at an even steeper discount.

Here are the top 15 products you should always buy online.

Designer clothing and accessories

Designer consignment is a big thing right now. You can find Prada handbags, Gucci shoes, and more for up to 70% off. You can buy from some online shops where all the items are authenticated, and you can return everything (except select items like swimsuits) when it turns out that you don’t like them. You can also get some bonuses. Some new shoppers get a $25 gift card. While you can occasionally find consignment pieces in local shops, it’s far easier to find the exact Kate Spade clutch you’ve been lusting after by searching online. You can get quality designer clothing at an affordable price and the item will be delivered to your doorstep.
