Tax free when a company buys them. I prefer the free snacks even at an even money exchange, but realistically, you'd see about $12/week on a $20/week rerouting.
If $8/week is something that affects your decisions, you might benefit from unionizing for higher pay. ;)
If you want to play the tax game, let's talk about reimbursing large purchases like a vehicle, personal laptop that you aren't monitoring, education costs, or housing. There isn't a situation where I'm going to care about snacks.
