Well, let us hope that those who could not find what they wanted at Argos turned to Amazon as today's news is:
"Amazon celebrates record Christmas
Online retailer Amazon is celebrating a record Christmas sales haul after its UK arm delivered as many as 480,000 gifts a day.
Amazon.co.uk shipped more than 256 tonnes of goods on its busiest day - with a Royal Mail truck leaving one of its three distribution centres every 15 minutes."
Incidentally, the Argos site currently shows no Hornby product as out of stock, only that some items have to be collected at stores.
