Amazon apologises for the delay in delivering your order. However it is now available for collection anytime. You'll find it hanging in high voltage powerline only two blocks from your house. Thank you for your order.

They're having a laugh. It's a totally impractical idea. Sounds like of those publicity stunts used by certain airline chief over here.
Imagine how long before every tree and powerline would be festooned with the things. On windy days they would be blown into the next State or through your bedroom window. The bodies of decapitated dogs and children would litter the streets. People would shoot them down in droves.
What if you lived in an apartment on the twenty second floor or even the first floor?
It's a hilarious idea but not very sensible.
