The normal price for a shirt is 4 for $200 on sale and ties are also $40 each on sale so this is a great deal.
I am a big fan of Tyrwhitt shirts and I have been slowly replacing my shabbos 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.
