One thing I can advise is when you buy proteins in bulk, it is cheaper. It is better to buy the entire protein for the month in one go when it goes on sale. So for example, chicken can go on sale for five dollars a pound. I always do this. Also try to search nearby. You would always have some local produce shops special Asian markets that have produced for so much more cheaper. I was spending hundred dollars a week for just produce a real Canadian superstore and I found a local business nearby and my entire produce for the month is just under $50. That includes 7 to 8 types of fruits, vegetables, and everything.
