Satin pillowcases
If you shop around, you can easily find a set of two satin pillowcases on Amazon for only $5.91, which is less than $2.96 each. It’s worth noting that different colors and patterns often come with different prices, so if you are open to random colors and patterns, you might get a great deal. At Walmart, you might pay a minimum of $9.95 for two satin pillowcases, while at Target, you could pay $5 each. Since we’re at it, I really have to share with you my favorite set of satin pillowcases. Trust me, getting this set was one of the best decisions I ever made!
Diapers
Amazon’s prices on diapers are really great unless you get an amazing deal at the drug stores using coupons, in which case it can get even better. I’ve calculated Amazon’s prices per diaper many times before and discovered that they beat even the prices at local stores after coupons. If you want to find the best price, just do the math and find the lowest price per diaper in any size.
Books
Amazon probably has the best prices on most books on any given day, especially when they have their special book promotions. So if you don’t mind buying used books, you might save a bundle on those, too. However, make sure you note all the shipping prices on used books because, in some cases, it might not be a good deal in the end.
