I have found an online book store which accepts payment through unverified PayPal. BetterWorldBooks.com is where you can buy books - old and new - for fair price and get it even shipped for free! Yes, the site makes international shipments and that too, for free.
Moreover, it is not just a company making profits off your purchase. As the name suggests, they are also helping to make the world a better place by helping the people in need. Every time you buy a book at BetterWorldBooks.com, they donate a book to some one in need. So, you are not just paying for your own need but for someone else in need as well. They have other literacy campaigns as well, where they donate some amounts to the organization, which are in someway or the other, involved in promoting education and literacy in different countries of Africa, Asia or other parts.
You can choose from over 8 millions of used and new books on the site. As I have mentioned before, they offer free shipping worldwide and the item gets shipped relatively faster as well. It took about a day for my item to get shipped from their warehouse. If you are from USA, you can also choose expedited delivery, but as always, that would cost you more money. The book I had ordered, took around 27 days to reach to me, here in Nepal. That's very normal, by the way. And I had to pay no customs or any extra charge, the payment that I made to the site was the only payment I made, not a single dollar more than that. I had ordered a used book, and it was in very good condition. So, you need not worry about whether the used book will be in readable condition or not.
The site does not copy the shipping address from your PayPal address details, you have to enter the shipping address later.
As you can see, the payment was made from a PayPal account with PayPal funds; I had used an unverified PayPal account for the purpose. So, if you are looking on how to spend your money from unverified PayPal, BetterWorldBooks just might be the place for you.
