Thanks for all jms advice!! I finally sent an email to Bossini And will handle by them. Seems their online shopping service need to be improved!! Unsure if all products available . Current order 18 items ~2600 and discount ~1800!!! Really worth! Need to wait their reply!
The system is so stupid that it can't display what's wrong with the order! I bought over 20 items, luckily, I tried just 1 or 2, I found out which item was out of stock.
