Replacement Cover for polytunnel

[dbsevern]

I have a cheap ebay polytunnel, that I bought 7 years ago. It has given me good service, but the cover is now in need of replacing. Does anyone have any suggestion where it is best to source a replacement cover, or should I try to cover it myself with plastic sheeting. It just has the mesh PE cover it came with at the moment, but don't seem to be able to just buy a replacement cover and I don't really want to buy a whole new frame and cover just to use the cover. Any suggestions or experience?

Should have said, it is just a small 2 x 2.5 m tunnel, notthing large.

Have you tried a few recycling centres,they might have big plastic sheeting,our local place leaves things at the side that can be reused.
