I would go for don't have promotion right now hehehe yup uncle david slow in catching up with latest model kekeke erk 450 already.. i dont think so.... sure promotion price this one.. ..
Last two weeks.. Mr David scared that customer will miss use his promotion price to sell to another badminton shop... That is why his pricing is always change...
Dun thk uncle david dealing with fakes or selling used stuff as brand new. MS is one of the established shops jus like the other big fellas, aj, hock eng, sp lee and racket world. Selling at cheaper price, translate lesser margin. Try buy one at RSH and see how much rrp off they offer. Not fair even to suggest it, someone may read it wrongly and start spreading it ard.
Just say u stay nearby PJ area which only knows recently the Modern Sport.. Also can ask first all the price of other racket....
