I thought I already had the golden and the gold Anaconda paintjob from the previous promo and this year's free upgrade, but the store says I don't. Oh well...
Be careful about that.
I have the Gold Anaconda paintjob and was given the Golden one by FD a few weeks ago. But according to the store I don't have that skin. In the game it IS there though.
Looks like a bug in the store, but be careful otherwise you could end up buying something you already have.
Check in game first if you even think you MIGHT have a Gold (or Golden) skin.
