Allotment shed: The cheapest way to put down a base for the shed floor to stand on?

[Val G]

[color=darkred][/color]I wish to build sheds in my allotment but I cannot afford to pay a lot for the base. Can someone tell me the cheapest way to put down a base for the shed floor to stand on? Thank you in anticipation.
