For the Chinese 11.11 sales event, the foldable handset went out of stock in no time despite its rather asking price of over $2,000.
However, Samsung didn't go into much detail how many units it moved in the second batch.
The good news is that more stock is coming in fairly frequently so if you are set on getting a unit you will get your chance sooner or later.
