Its iconic polo will never go out of style, and between brand revamps and innovative collaborations, it's always in the fashion consciousness. That's why we're always on alert for when Amazon has sales on Lacoste. Right now, bestsellers, including that classic piqué polo, are up to 40 percent off on the mega retailer's website. Still, the original polo René Lacoste introduced to the tennis world back is the belle of the ball here. Stock on that one fluctuates, so if you see a price you like on the polo, buy it before someone at Amazon or Lacoste changes their mind.
