It's off topic but this isn't exactly a hopping thread so I'll share my thoughts.
I think they just do sales in major cities to clear merchandise from about 5 seasons ago. If they have them in smaller markets they seem to be tied to relocation/new stores. They don't seem to be on any kind of markdown schedule like the other brands but they also make fewer items and have less stock. Plus I suppose they feel their stock is more timeless and therefore doesn't require regular clearance. I was looking at a RTW piece and my SA checked stock in the US as I wanted to wait on it and there were only 3 pieces in the US and 12 globally. Some pieces really are "small batch". Glad to hear you've been enjoying KoP, I think they're great!
