Quick! does anybody have a new tub of Anchor spreadable butter; 500gm?

[examtaxi]

I have just bought 2 of these on special offer (dd and I are making flapjacks). I have just weighed each tub on my scales and the weight is 400gms.

Are my scales wrong, or is this special offer not as good as I thought it was?

It's the same with butter, honest I thought it was me but instead of 250 end up with 215 , robbing sods.

Your scales won't be as accurate and will have been marks as "not suitable for trade" or something similar. 100g seems way out though.

My 250g of Waitrose butter weighs 254 g though. WIth the paper wrapper.
