Depending on just how much junk you're dealing with, you might not have the energy to create separate listings for each one. If you don't mind a slightly lower price, Decluttr makes it even easier to sell your old CDs, DVDs, Blu-rays, video games, books, and tech gadgets. Rather than hawking your items to other users, you sell directly to the company behind the app. To do so, either scan the barcodes of your items or enter their details manually. Decluttr will offer you a price, and if you're happy with it, you'll receive packaging that lets you ship your junk for free.
