We have noticed some things have gone up in price. Our mortgage for one! 8 years ago the goal, was to keep groceries below $200 for the week. This includes food, pet needs and cleaning beds. Now, I try and keep it below $300. Cleaning and hygiene needs have increased substantially, especially since the shortage during the pandemic. What we do though, is buy nonperishables when they are on a very good special and store them. Our Harry Potter cupboard is stocked with TP, Paper towel tissues and toiletries. our laundry has multiple boxes of detergent and household cleaning products. And we have a substantial store of pet food. I DO keep a mental track and don’t buy more if I know we have loads, even if they are on special, but it’s a good system.
