They gave you a random one if you use their built in wallet. I'm assuming with premium you will be able to select how it displays.
I've seen so many people with primal Lightning addresses even before this premium thing was launched

Correct. I randomly got bravecobra6 as my Primal lightning address - works fine. To customize that with my preferred handle I would have to claim it and pay monthly for Primal premium.
I was VERY tempted until I connected Coinos to Damus and everything just fell into place.
All depends how badly you want a custom Primal address?
It felt a little weird to pay for the privilege and prestige of the Primal check mark. A little to X’ish. But it’s good to fund development of a platform we all use, so there’s that - and Primal 2.0 is pretty fraking good! 
tbh, I didn't know premium existed
Yeah - several of the OGs and people Primal want to promote have custom (premium) handles. I tried multiple ways to select my Primal LN address, but kept getting randomly generated ones, then I realized it was a premium thing. It might still by invite only?
I could only ever use my Primal wallet to zap nostriches so that locked me into the Primal app. Then, with the help of some amazing folks here, I stumbled into why Damus on iOS had no zap icon (whole thing). Figured out thru trial and error how to enable the zap icon in Damus, then connected a Coinos wallet via NWC to Damus and was off to the races!
Yeah, I guess you have to pay now. It was free once upon a time
