For some reason the name “Rexall” popped into my mind a minute ago and I had to see what http://en.wikipedia.org/wiki/Rexall had to say about it, to be sure the topic was worth a thread. I also did a keyword search on “rexall” to see that there have been quite a few mentions in posts, but no specific threads devoted to the concept/name/whatever.
So I thought I’d start one. Whatever Rexall means to you, or makes you think of, is okay for this thread.
For starters, do you know where and when the “Rx” thing got started?
