Swing tickets are one of the first things people look at when buying a product, hence their importance.
If you were looking at a high quality garment and it came with a cheap swing ticket for a £1000 price tag, not many people would be convinced. However if your buying a top quality garment with a top quality ticket to go with it, the customer is more likely to be tempted. They are buying the full package and experience.
Buying a t-shirt from Primark has a totally different feeling than buying one from Louis Vuitton. This is not just from the price as I personally would say it hurts more, but the experience you get. As soon as you pick up the garment the quality swing ticket makes you realise why you are buying that t-shirt in that shop, not the one in Primark for £3.
