Can someone sell their temporal lock boxes?

Yes but right now they have a very low value on the exchange, when they were introduced they could get you 20k each. Its the keys that are valuable and those you have to buy for zen, which you pretty much have to buy with real world money, currently you'd need about 18000 Dilithium to buy the zen for 1 key.

The market for used stuff between players is the Exchange, there are terminals at most starbases, at the Sol Spacedock its in the blue area.

wait a few weeks o so after the temporals stop being dropped and the price to sell them could go up. after all people seem to really want the temporal sci ship, if not mainly for the console, especially when comvbined with the temporal destroyers console.

When the temporal lock boxes first came out I was selling them straight on the exchange for 30k, only lasted a week or so though.

If you have space, keep them and sell them on once they've stopped dropping - i think I saw ferengi ones going for almost 100k recently.

Hmm, I have about 500 socked away.

You keep lockboxes in your socks?

ewwww..... I wouldn't touch those lockboxes with a 15 foot cattle prod.
