Wow i can get 5 freshly fried donuts for that! Failing that sainsburys in my opinion do the finest jam donuts knowen to mankind. Sadly this knowledge has been gained at the expense of my godly physiec. I still have the body of a god...... just a shame its Buddha
Like most things in life - You get what you pay for.
Sure Sainsburys/tescos/asda doughnuts are nice but these are like a "Ford" type of doughnut - the Krispy Kreme ones are "Mercedes/BMW" type. Yes they are £1.85 each but if you buy a case of 12 in different glazes then you will be a fat whatsit very soon.
For the price try one and see - its your decision after all.
