So, as long as I don't use it, I won't be offered another one? Thank you.
That is correct, and not just "use it", but be done using it. In other words, you won't get one as long as you have one either in Smuggler's or currently active.
Server 1 was always friendly to this item, and it was possible to buy it alone (for $10 I think) and in packs. If you go a few days without having it offered after it has expired, ping me via DMs with your in-game ID (the one from the Help window) and I'll ask my contact to check.
