Kobo has just signed a deal with Visa Checkout, that allows people to get a few free e-books. If you use this new alternative to Paypal, you will gain $10 in free credit that will allow you get a number of digital titles.
The Visa Checkout promotion will run from June 1st to June 20th. When you purchase an e-reader or e-book you will instantly get the $10 credited to your Kobo account and then you can spend it on any e-book you want.. It is important to note that you can only earn the credit once, not perpetually with every purchase.
Visa Checkout is a relatively new system that allows you to tie in your credit or debit cards and use them to pay for things. The payment platform is trying to secure partnerships to get it going. Recently they did a deal with Chapters/Indigo that allows people to get 20% off a single purchase. Many people have used this to get a big savings off of a Kobo H2O or Kobo Glo HD.
