BkeyI was late by a few seconds because I joined and decided to change the cable length last minute, so I had to cancel the initial order and when I wanted to place a new one the drop was already inactive :(
BkeyThey send an email of a good amount of drops, daily. They also send a separate email to each person who requested a specific item. And if the item is currently being dropped, you can hit the remind me button that is usually below the Join Drop button and it will send you another reminder by email 1 day before it closes.
