Sometimes popular affiliate programs like these have just way too many people trying to sell their service. I personally went to sitecare.ca and asked them if I could sell their service and I couldn’t be happier! So find a service you believe in and go for it!

Most businesses require startup fees as well as a cash flow to finance the products being sold.

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.
