Old paving slabs (Wisbech PE13)

Before these go in the skip can anyone make use of any of them? The base for a garden shed or greenhouse? A path on an allotment or vegetable patch? A single one for a water butt or compost bin?
They're approximately 60cm x 60cm. 13 grey/buff. 3 red.
They're coming up the end of this week/beginning of next week and will need to be collected before the skip goes next Thursday.
