Where can I buy frozen gooseberries?

Does anyone know where I might find some frozen gooseberries?  Obviously there aren't any fresh around at the moment, but all I can find is the tinned ones.  I found a website with a link to regional farmshops which suggested they might be a source, but the only ones in my area don't seem to do much fruit (which is strange, given that there are plenty of fruit farms about!). 

Many thanks for that ... unfortunately, despite my ID, I don't live in Cheshire any more (sadly left about thirty years ago!).  However, your suggestion of trying the smaller local supermarkets (as I seem to remember Booths is) sounds like an idea, so I'll give it a go.
