Trying direct sales too

I have placed a button on my Books page which takes you to Paypal, where you have the option of paying me directly through their service for a copy of 'In the Valley'$1.99. same price, but this way I keep all the revenue, instead of 35% from Amazon or 50% from Smashwords.

I will have to do a test to see if this works, but should go
1) someone gives Paypal $1.99(CAD)
2)Paypal notifies me by e-mail
3)I send them a PDF copy by e-mail

I don't expect to sell many, or in fact any, this way, but I want to try the system. If everything works well, this could ramp up; with ISBN nos to use for other books, who knows?
