sax.co.uk does have offers regularly and , at least once a year they have some major Yanagisawa offer of some sort, not long agoI bought a 65 neck for alto at half price and now I've bought a sopranino metal mouthpiece.
This , of course, could be due to overstocking but more often than not it is a way to generate interested in a shop and a product not unlike the supermaket's periodical special offers.
Yanagisawa is part of a sales strategy that sax.co.uk is wisely carrying out.
Supermarkets compel their suppliers to a number of things, including a certain amount of " special offers" every so often. It is part of the deal that also includes a number of fees that the the supplier pays to the supermarket (most consumers wouldn't even know that a supplier is actually paying a supermarket to sell their products but they do).
You as a customer will get the advantage of buying cheap, both the shop and the factory are moving some stock and they are not doing so at a loss, at the same time interest is being generated and the shop might actually sell many more other items simply because more people are being brought to do some browsing and ordering.
Gettting the people in the shop (on line or not) is one of the most difficult and expensive things these days.........
