I wish I had bought a dozen blocks when they were easy to get. Maybe it would be wise to stock up now. You never know when they will become unavailable again.
I have a new monetary reference courtesy of this thread, a "block", as in: "We just made the spring tuition payment for the oldest of my 3 kids who's a freshman at a state university and it was 2 blocks."
Much as I hate to admit it, I'm so not the target audience for any of the new blocks at their current -- and foreseeable -- price points.
