This is such a great idea for your busy UPS, FED EX or USPS delivery people.
I live in the midwest so the temperature here can be miserable and my delivery people are always working overtime during the holidays this is a nice way to say "Thank You"
Tip* Make sure that if you put out sodas/water that you take them in at night if it is cold outside.
If the sodas freeze they will explode and water will expand and break open.
