I'm being weird again!

I'm keeping a list of everything I harvest, including the weight. I'm then looking up the price of the same things on the A$da website so that I can see how much I'm saving, bearing in mind the costs of the allotment and anything else I buy for it. So far in 2009, I'm almost half way to breaking even, which I don't think is bad considering the main harvest period hasn't got going yet.
Anyway, I've been picking redcurrants today, but they're not available in supermarkets at the moment. Does anyone know how much they sell for approximately, please? And if you could have a guess at the weight of the currants for that price so that I can work out the per kg price, that would be fantastic.
Thanks
