UPDATE 3.20pm UK: Argos has responded to reports its latest stock allocation was sniped by scalpers. Speaking to Eurogamer this afternoon, a spokesperson confirmed the chain was aware of today's issues but had currently sold out.
Eurogamer understands the exploit used by the scalping group to buy stock before it was placed on sale has now been addressed and future attempts to use this method will not be successful.
"It's clear our customers are excited for the new PlayStation," an Argos spokesperson said. "We released a small amount of additional stock and have seen huge numbers of customers trying to place their orders with us and we have now sold out."
