Tips on saving money grocery shopping?

It’s just me and my husband and we spend $250 (sometimes a little more) on groceries every other week. Which I feel like is a lot for just us 2. We have a baby due soon so I know the grocery bills are gonna start getting more expensive as we have to buy diapers, wipes, formula, etc. we usually shop at Walmart and try to buy off brand as much as we can.

Does anyone have any tips on how to save money when it comes to grocery shopping?

(I’m not interested in couponing. I simply don’t have time)

Thanks!
