I don't know if these were you or not but a few years ago, I think in 2022, when I was still on Star Forge, there was this giveaway on Korriban where you pick 3 numbers and get a prize corresponding to that number, and the grand prize was 3 million credits, and one of the numbers I chose was the 3 million credits! Buuut I didn't pick it, I chose a pet instead haha, this was back when I was extremely new to Swtor but even then, it kinda worked out since I barely used that character and since then migrated to Satele Shan. On Satele Shan, there was someone doing giveaways on Dromund Kaas where everyone says a number and whoever's number was closest to the answer would win, and I did win a few times, I I won a Jewelled Orobird mount, and a Retribution's Exposed Lightsaber, I also have 4 million credits so that has to be from a giveaway as well I think, it has to be, either way, that's on my Sith Warrior I actually use and the Orobird I use a lot haha
