And to the real topic of this thread (and not the Hermes side topic):
Pay what you want for the ties you like. I don't buy any tie with which I'm not absolutely in love. Every one of the ties I've bought in the last, say, decade is a tie I would where literally every day if it weren't for the fact that (1) I have many other ties about which I feel the same, so I work them into my rotation and (2) people would look at me weirdly if I did.
Also note that if I buy a simple staple rep tie from J.Press at full price, it is 50% cheaper than buying a Charvet tie at 20% off. So I'm not sure that the discount really is the right way to look at this. What's important is how ties look on the wearer, not how much they cost, or even how fine the quality is (SHOCK!)
As Foof has demonstrated on his blog, a $50 tie from Press looks fantastic. At the same time, I find ties which I think are horrendously ugly at all price points -- from the $12 ties at discount stores to $200+ Brioni and Kiton ties I see. FWIW, the most consistently gorgeous ties I've seen which are also conservative come from makers like Marinella, Cappelli, and Press. Simple, understated, classic, not attention-grabbing. Drake's is also great, but there's wider variability there (sometimes they have really ugly ties, especially the ones made for Barneys).
I also like many of the ties sold online (made in NY) by Mountain & Sackett.
