Amazon UK used to be no limit but it's now £10 limit. However, this can be bypassed slightly by adding any media item (for example CD/book/DVD).<p>A lot of people had fun finding the cheapest piece of media, I think someone found a warehouse full of 10p cassette tapes at one point being sold by a company and handled by Amazon, thus giving people 10p shipping for orders under £10.<p>Regardless, if you have 4 friends you can split the cost of prime up to 5 ways (yourself + 4 friends) for next day. In my experience, at least, this has worked even delivering to different addresses. You have to list them as family members, 3 of my "family" are housemates and a fourth lives down the road.
