Amazon is very safe. I'd put them extremely high on the "safe scale". And there are many benefits to having an Amazon account. Not only can you purchase, but you can join "communities" (such as reading, movie or music communities) and post on the discussion boards. Your profile page has some beneficial stuff too. Like recommendations and wish lists for yourself and wishlists for those close to you. Amazon will even send you reminders via email when your friends' birthdays are coming up. I love Amazon.
The amazon is a sacredly unforgiving place where the morning dew turns to muggy stew in the air as the toucans get higher and louder off the aroma. that's about as beautiful as it gets before the conditions cave in on you like a a pile of drab olive green army gear that fell out of a stuffed closet at home. Even when the underwear came in the mail IT WAS NOT CLEAN. every god damn pecker pouch was pooped in like a silly prank against me.
