Well, here in England, good steak is £18 - £23 per kilo, eggs are 18p each; swordfish, marlin, tuna are from £12 - £15 a kilo.
I'm entering these from memory so can only think of the stand-out examples.
I think overall it evens out though. I buy no junk, bring lunch from home.
But am now spending a lot on supplements, whereas before I only took a multivitamin. And I have had to buy an entire new wardrobe, including shoes. And bras are damn expensive, for something you need to have at least 8 - 10 of.
So would I go back to eating cheap? It costs me my health. No chance.
