If you go to ctshirts.com/nigel (I agree, kind of random, but you won't find the deal from the regular site). you can get Charest Tyrwhitt shirts for $40 and it comes with a free tie. Shipping adds another $9.95 so it comes out to $50
I am a big fan of Tyrwhitt shirts and I have been slowly replacing my Brooks Brothers shirts with Tyrwhitt shirts because they look much nicer, last longer and Brooks Brothers seems to have gotten rid of their unlimited return policy. Too many people like me.
Tyrwhitt shirts are also backed up by JK.
Start your purchase from Ebates and you might get 5% cashback as well. You will still get your normal cashback from your credit card as well. The deal is only from this link so I would go to Ebates and on to the Tyrwhitt like you would regularly then go to ctshirts.com/nigel again and you still might get the 5%. It's worth a shot!
