I've been looking at these guys too...pretty good wholesale prices for 100% authentic goods, free worldwide shipping helps. I am in the research phase, trying to discern profit potential before I buy, but looks good so far.
For anyone who has used them, are you seeing satisfactory profit levels from the high end glasses? I am guessing turning over an inventory of high end sunglasses (or anything for that matter) takes time, and I am just trying to decide if I should sell one pair a week of these, or turn and burn something lower end. Have they been moving?
