Yes. that is cheap.For what it's worth, the update does not appear to be locked behind a higher tier, so the lowest monthly subscription (shows as $1.32 USD on my end) gets you immediate access.
I was about to go and subscribe, but sadly none of the registration methods is a go for me.
I don't want to associate my social networks/big corp accounts or my phone number with boosty.

Are there alternative methods for registration ?
