We used Stork at home too!
I can't remember what brand the school used we had to pay for the ingredients we used. Though my cookery teacher always had a go for going to slow. Though as we had gas at home, at school I had to use the electric cookers. To this day I am not keen on electric cookers.
I have just ordered a Margret Dabbs Foot File, although it is more than on Amazon it comes with more replacement pads. One of the reviews on Amazon alerted me to it.
My previous purchase was Alpha-h Eye Complex Duo as it was good price.
I find Prime Day and Black Friday offers are bit hit and miss. I have found that over the last few months you have to be careful, some of their prices have been bumped up.
