I made a quick stop at the grocery store today. We were both in the mood for potato-leek stew so I wanted to get more leeks before our next regular shopping trip. Whenever I am at the store I check to see if there is a store special on anything we regularly use and which stores well. Today the brand of olive oil we use (and since we are vegans we use olive oil quite a bit) was on sale -- 23% off. So of course I brought a few bottles of olive oil home along with the leeks.
As I was putting the olive oil away (we always put the most recently purchased items at the back the shelf and move the oldest to the front) I realized that everything in that particular cupboard had been bought on sale. We can afford to take advantage of store specials because we have a freezer large enough to hold a substantial amount of food and a bank account that allows us flexibility in our budgeting.
Those who are poor, those who barely scrape by from week to week, and those who are living on food stamps cannot take advantage of the same specials as do we. So those who least need to stretch their food budget are most able to do so.
Yet another invisible tax on being poor.
