Tickets4U acts as an intermediate trader of Lady Gaga tickets which means that the Lady Gaga tickets offered are being resold. Tickets4U prices are therefore based on the principal of supply and demand. This means that prices can differ from the original sales price which is printed on the Lady Gaga ticket.
When availability is limited, Tickets4U generally pays higher purchase costs which results in a higher retail price. However, in some cases it is possible that tickets are sold below cost price.
