We do. We average around $150-$170 per week buying for 2.5 (the half is for our King Charles Cavalier). He turns his nose up at tinned or processed food making it an expensive shopping trip each week with kangaroo and chicken fillets no less.
Although we buy a lot of fresh produce and seafood (I eat fish on a daily basis) we also ensure we have a fully stocked pantry for emergencies. If something we use on a regular basis is on special we will buy multiple of that product and freeze.
I find I can easily spend $10 just in fresh herbs - as much as I continue trying to grow herbs such as dill, basil and coriander, I invariably still need to include bunches of herbs on my weekly shops.
It would certainly be interesting to do a shopping list comparison !
