Seriously.. Amazon knows about Bitcoin. They don't see it as a good direction at this point. When they do, they will start accepting it. Petitions won't do anything, and hitting the 5000 signature mark is meaningless.
Maybe because they havent had 'enough' requests from their customers.
Trust me, good retailers listen to their customers. I worked for quite a few over the years and Ive been to plenty that do and dont listen. The results are predictable.
While 5k signatures probably wont get the whale off the beach, its will register on their radar and hopefully set off a chain reaction somewhere:)
