Yes look out for the sales they will save you money and stock up on diapers but don't throw the recipes in case you can exchange for a different size. Don't buy like 6 boxes usually baby will grow out of a certain size as they grow
Look out for sales. Like Target is doing a buy 2 boxes of diapers, get a $25 gift card. If something isn't on a good sale, don't buy it and stash the money away for later when you actually need the item or for a good sale. Check out the clearance racks in stores for clothes and towels too! What I do, is find something on clearance or sale and check the price against what it is on Amazon, then decide if it's worth it or not.
