Another way to make money if you only have a few days is to sell items on eBay. You can typically set items to sell in just a few days, and you can have the money in your PayPal account instantly. If you are going to sell on eBay, you have to have excellent pictures. To achieve this, make sure to take photos of your items in a place where they have enough light. Make sure pictures aren’t blurry, and write as much detail as possible in the item description in clear, easy to understand English.
Hunt for under-priced used books that you can sell online. Download an app that reads ISBN numbers so you can scan the barcodes on books. This will pull up the book’s current price on Amazon so you can see if it’s worth trying to resell it. Then, visit used book stores, thrift stores, and garage sales to look for high value books. Post the books for sale online using sites like Amazon or Ebay.
