Pez,
You don't say where you live, or work, but surely a lunchtime trip to a Post Office is not out of the question?
Currently this government is about to close upto 2,500 branches, so, its a case of 'use it or loose it'
Also, as Claudia says, you walk out a few minutes later with you new license in your wallet.
I ordered my licenses a few years ago on-line and they never arrived! Now I support my local Post Office.
