online shopping and finding good deals on everyday items

Hey all, I recently noticed that I spend way too much shopping online for daily essentials without checking for discounts first. The other day I ordered some household stuff and realized later that I could have gotten a better deal if I just searched a bit more. I feel like there must be a smarter way to save without spending hours hunting for coupons. Does anyone have a routine or website they use to make sure they aren’t overspending every month?
