I just got back from Macau and Guam last month. Most of my LV purchases I do in Guam since I find it's really cheaper than Manila (stupidly horrendous mark-up) and TAX FREE, and notably 30% less than the prices in Korea and Japan. Whatever price indicated in the US website of LV, that's the price in Guam. As for Macau (LV in Four Seasons, The Shoppes, Duty Free Shop), prices are about 100 to 200$ difference than in LV (Duty Free Shop) Guam. I heard LV DFS in Saipan is cheap too!
