Extra Kitchen Faucet

While I was taking our breakfast this morning I am at the same time listing things I need to buy on my planner. It was a to buy list. I was not listing it to buy immediately but a prompt for me to work harder so that I can buy those things. My list includes two kitchen faucets. Our current faucet is broken again. So I want to make sure that I have a spare one. It is better to have an extra one right?
