I noticed something in Sara Noel's example... I thought most individual-sized applesauce cups were 4-ounces. So Motts have had a size reduction and that's just shy of a serving amount (4-ounces of applesauce is a serving).
Individual sizes of anything are nearly always more expensive than making your own portions from a large size container. That's why it's important to figure unit price (how much each is per ounce).
The individual servings-size in the example are .07 cents an ounce while the larger size is .037 (almost .04) cents an ounce. That's a huge difference in price per ounce....
Not to mention you get 6 servings from the individual size containers while you get 12 (4-oz.) servings from the 48-oz. jar. If you would have a problem using a 48-oz. jar, you can freeze the applesauce in small plastic containers and make your own single-servings. They thaw pretty fast (overnight) in the refrigerator.
We dehydrate what seems like "tons" of apple slices (free-for-the-picking, so the price is great) and use them for homemade applesauce, apple cobbler/pie, and snack food. That's another cost effective method.
You can also make applesauce with fresh apples at home and freeze it in portions.

By making your own applesauce, you can also control the ingredients. Did you notice any high fructose corn syrup in the recipe for homemade applesauce? I avoid foods that contain high fructose corn syrup, opting for a low-glycemic, natural, honey-like sweetener - agave nectar, instead.
Last tip for homemade applesauce...
Add sugar to applesauce EARLY for chunkier sauce. Add sugar later for smooth applesauce.
