Certainly not for everyone and I don't partake in too much Tom Ford, but the few times I like to splurge, I prefer to do it at discount. I believe the retail on these is $590+ if I recall correctly. Admittedly most of my dress shirts are T&A, Zegna, RLBL and Canali but the few TF shirts I do have always stand out when I wear them....not to mention the ties. I'm sure there will be another price drop, but there's always slim pickings for my size (17) by that point.
The retail price usually just shows how overpriced the item was before the discount. Besides the idiots who feel good about themselves for owning ultra-expensive items, I doubt that anyone pays anywhere near that price. They only keep it that high as a marketing ploy to make people think that it's a steal when they lower the price to $350.
