I gift my novels on Amazon to those who like my work, or tell me so in PM's on the boards. It really pays in the long run. They will usually give a review. It's only a few dollars. You've got a fan.
You can't do it on B&N, unfortunately. But when someone likes my novels it's the greatest reward of all.
