One of the benefits of buying bttled and jarred packaged goods is that you can purchase them from many different stores. You can also find them in a variety of sizes and prices.
Another benefit is that they are easy to transport. They are lightweight and come in small, compact containers so you don't have to worry about lugging around heavy items or spilling liquids in your bag.
Finally, the convenience of packaged goods is a big advantage. You don't have to worry about packaging things yourself and they come with the ingredients you need to make a meal or snack - sometimes even with an easy-to-follow recipe on the package!
