Just reserved and picked this up at Argos - but at the checkout the total was £330 - they have priced it wrong - but with the printout from the reservation they honoured the £287.34 price.
The Mega Pack is normally £40 and Little Big Planet £40 - so I think this is a good deal?
If you don't mind risking delivery - you can get use the £10 voucher off making it £277.34.
Don't forget Quidco at 1.5% and free delivery - Bargain!!
