The initial approach was to offer two round trip tickets to European destinations; this promotion proved extremely popular with customers. Few customers used the vouchers, so Hoover expanded the options to include destinations in the United States. The addition of American locations caused a surge in consumer response because the airline tickets held an approximate retail value of £600 and could be attained for an outlay of just £100. Consumers were increasingly purchasing the cheapest products available to satisfy the £100 requirement, sometimes not returning to pick up their order. Hoover had to increase their production and hire new employees to meet the increased demand. Hoover had estimated that they would receive 50,000 applications, but the final total was around 300,000.
