Just purchased a pair of Darlton wingtips in-store. $473.02 after discounts, $515 after tax.
In store, basically all blue label is for sale. Not sure about things like sunglasses. I thought about buying a couple of cashmere cardigans (included in sale, but cashmere cardigans are never really on the website at all).
Yes, just go to the store on those dates and tell them you forgot to bring the card and have them enter MAY0511 as the discount code. I never bother to bring the card with me.
