Hi and welcome. Most of the bags never go on sale - not the Birkin, the Kelly or to date, the Lindy and Jypsiere. Usually it's items like the Garden Party and discontinued bags, sometimes bags like the Trim, or the Bolide, Plume or Omnibus. Ready to wear and small leather goods and shoes also show up. Also silks and cashmere scarves. The selection is different year to year, from sale to sale and country to country. Different countries have their sales at different times and they are usually not in the store but at a separate location.
