Except for one or two specialised skin care products, I buy most of my toiletries from the supermarket. As such, my grocery budget has always been designed to include those.
However, I am finding that I am either going well under my grocery budget or well over when I have to buy certain toiletry products.
For example, today I bought my groceries. I usually have a $65 budget for groceries. So I bought the food I needed. Fortunately I didn't have to buy any meat this week as I have plenty in the freezer. I also bought some deodorant, toilet cleaner, starch and batteries. This bought me in just under $65.
However, this week I had to buy new heads for my electric toothbrush which costs $14 for a pack of two. Now these heads last a while, so I only need to repurchase two or maybe three times a year, so they are not a regular purchase. However, when I do buy them, they tip my budget over. Admittedly it's not a huge problem because I always have spare money in my account to cushion it, but what if I didn't.
I'm clearly not very good at purchasing these one off or once every so often more expensive purchases. I was thinking I could make my grocery budget and toiletry budget separate but that still wouldn't help with the more expensive purchases.
Does anyone have this problem? Can anyone offer any advice to get it more under control?
