Are snack bins worth it?

For those mommas that do the “snack bins” is it worth it? And how many snacks do y’all put in there for 6 & 10 year olds?

When I used to do these, I put two snacks a day and a drink of their choice for every day. If they are it all in 2 days, then so be it. It was not refilled till the end of the week. There was still yogurt, veggies, fruits and stuff like that in the fridge, but the requested cookies, crackers and chips were gone till restock day.
