Title is question
If I buy the 6mo/3mo premium code, can I activate both and have them stack?
You can activate both, but they don't stack at the same time. You'll want to activate one and use it, then when it's over activate the other. They don't expire and stay on your Billing page for you to use any time, so there's no problem with activating one now and one 3/6 months from now. :)
Alright, thanks!
