I did think about putting where I bought things, but I figure that's very temporary information and I have enough trouble keeping other things up to date.
Often I think a product has been discontinued only to find it appear in a couple of newsagents a few weeks later.
Generally I buy products from the bigger supermarkets and Woolworths, in fact Woolworths has the best track record when it comes to the greatest variety of products. Of course there are probably a quite a few things listed as current when they should be in the discontinued section (my bad ).
Anything I can do to make voting easier just let me know.
