I just noticed I received a #000 from MI this week and the postage affixed was only 0.58 fwiw. I guess the per cost price of one letter envelope vs one #000 certainly adds up over time, but if cost is not an object for someone, going "on the cheap" like I do isn't important. For me, cost is a significant factor. If I can find an alternative way to do something and pay less, my limited budget thanks me.
