Ok, it somehow did not occur to me that there was a full range between "Safeway - $32" and "cucumbers - $1.20, cheese - $7.52" etc. Totally better to track by department instead of item. My husband and I are just setting up our first home after moving from a 600 square foot apartment so we have been buying a lot of long term items (not to excess, but I can finally have more than 3 spices and more than one oil, and buy the Costco sized rice, etc.). I guess it does still even out over time but the last few months have seemed pretty skewed.
