How much do you spend on Groceries?

So many people are talking about the high cost of living so I thought would check our spending on groceries over the last 18 months. We shop for 3 adults and now spend about $1,000 a month for groceries. So, about $333 per person. Probably 75% of our groceries come from Costco. Then we look for sales at Superstore and Safeway and a few specialty stores. We live in Edmonton. How does that compare to what you spend?
