Looks like it's actually $249 if you don't own anything, $149 for an upgrade, and $99 for a MAXgrade, whatever that means. Not sure if that's the exact same as before or not, but nice they brought it back and thanks for the heada up!
Edit: it is indeed $249 outright, and only $99 if you already own a MAX product.
...but, if you buy Sample Tank 4 MAX currently on sale for $49, that counts and you can buy the MAXgrade for $99. And I had $20 of Jam Bucks for signing up I think, which let me take another $15 off. I should have taken $5 off the Sample Tank purchase as well, but I got studio max for $134.99 all in which feels pretty good.
! Wank the plank!
