Tesco will offer PlayStation 4's on a first come, first served basic at 150 of its Extra stores for the machine's European launch tonight.
No preorder is required, but stock will be limited to one per customer, and Tesco has its own postcode checker to help potential customers work out their nearest store.
London outlets with day-one PlayStation 4 stock include Tesco stores in Surrey Quays, Lea Valley, and Purley. Other major branches in the UK include Stretford, Stockport, West Bromwich, Shoreham-by-sea, and Bournemouth.
Alongside Tesco, Asda is offering walk-in stock at 155 branches, and Sony themselves are offering to sell machines at midnight if you can make it to Covent Garden.
The PlayStation 4 will launch across Europe tomorrow. In the UK, the machine will cost £349.
