We have some clearance marquees going cheaply on ebay.
These are from a batch of marquees last year but are brand new, still in their packaging (though some of the boxes may be a bit scruffy due to being in the warehouse for several months).
Bidding starts at 99p with no reserve. We normally sell these for £600-£700. They are slightly taller than our standard ones (30degree roof rather than 20degree) and have 500gsm PVC roof and sides. It’s a lot of kit for the money at normal selling price so these should be a bargain for someone.
