The other thing to think about is how many other non-RPi based orders there are spread across that 23,000...
The web server load chart RS published showed that hits on their site quadrupled on 29 February over a typical day"s load, so, there are usually tens (maybe hundreds?) of thousands of orders being placed for non-Pi items on a typical day (possibly worldwide across all of their partners?).
There"s an old Western movie with an appropriate title for this Other Day That Will Live In Infamy, "Bad Day at Black Rock"
The best things in life aren't things ... but, a Pi comes pretty darned close!

In theory, theory & practice are the same - in practice, they aren't!!!
