From HUKD:
"I've just spoken to a mate who used to be a Manager at Argos regarding differing info received from different staff and he said NO ONE (re members of staff) will know at this point whether the TPs will be sold instore only, online only, home delivery only, even top brass at Argos will not, AT THIS POINT, have decided how to retail them, the decision will only be made a couple of days before receiving the stock, as was the case with the Wii's and PS3's etc at Christmas (in the past few years). He also said when it is decided it will happen fast and as has happened before, staff will be able to buy one and one only.
He also thought, but could not confirm, that the rumours of Argos getting 400 in stock is not true, he said they will be getting more as Argos Group wouldn't buy just 400 at any one time, they nearly always get stocks of at least a couple of 1000 of big, very saleable items in demand.
I trust this mate, never let me down in the past. Make of it what you will.
By the way he is now a Manager at the DSI Group and says they are still awaiting further stock within the next couple of weeks"
