Stamford Cool Kids Club ("Club") is located in Leicester, operating in a building leased from Alderton Properties Corporation ("Alderton"). On 8 March 2021, Colocotronis Computers (UK) Limited delivered to the Club 10 PS4 games consoles, valued at 2,000 each, pursuant to arrangements which stipulated for "Sale or return until 31 March 2021." An additional term reads: "If the PS4 games consoles are unrequired, they should be sent to our warehouse at Station Road, Huddersfield HD2 1UW." As of March 2021, the Club were experiencing serious financial difficulties and fell into arrears with its rent, doubtless owing to low patronage and increasingly poor balance sheet in the preceding six months. On 29 March 2021, Alderton ultimately ran out of patience, came to the Club and seized a variety of gaming equipment, including the PS4 games consoles from Colocotronis. A couple of days later, Alderton pledged the PS4 games consoles to Victoria Leisure Park in consideration of a short-term loan. On 25 March 2021, the Club had written to Colocotronis, stating: "Stamford Cool Kids Club regret to inform you that they no longer provide kids online gaming services." In early April 2021, Colocotronis sent the Club an invoice with notes stating that the sum of 20,000 is due and payable for the 10 PS4 games consoles. Separately, Colocotronis said that the Club's message did not constitute a valid exercise of the Club's option to reject the PS4 games consoles.
