Very strange! This is not hidden deal and advertised on main page. Did you check if selected pair was out of promotion. I found this with very few pairs but it should print out of promotion message in product detail page.
It doesn’t work for me :-(
Quality and comfortable fitting perhaps make it value for money. Also note Returns is free, if dont like it for any reason then just send it back.
Can't believe the prices of some of them, even with 40% off the price is still way too high!
Eurgh, no thanks.
