Less than $9 from Amazon -- I just have to accumulate enough other things to buy so the order is big enough for free shipping. My wife may be willing to help with that.
rberg, I've been buying from Amazon for years, and three Christmases ago I signed up for a free Prime trial membership. Of course, I forgot to cancel after 60 days when it was up. But I'll tell you what, as often as I buy from them, the approx. $80 annual fee is a steal. Free two-day shipping on anything shipped from Amazon (gotta watch those third-party sellers), plus a slew of free TV-video-book content you can view or download to PC, phone, whatever--you don't need a Kindle. Also can share the whole thing with up to four other family members--wife and son, in my case, and they use it heavily too.
It's so nice not to have to find something else to buy to get the free shipping.
