Amazon Prime

Recently my free trial of Amazon Prime ran out and I am planning to pay for a subscription.  Not only is it very nice to have free shipping with no minimum purchase, but they continue to add other perks to this membership.  The first perk added was free video on demand.  It sounds nice, but the selection is fairly limited at this point.  The most recent added perk is free Kindle book borrowing.  I'm not sure how large the selection of titles included in this feature are, but it is just another way Amazon is keeping things interesting in the world of retail these days.
