Q:Origin Access Premier unlocks transfer to standard PC retail?

Hello,
Reason I am making a topic of my own if two fold. A reference to quote and a further point of discussion for PC players who discover that EA has specifically blocked Deluxe Edition sales from retailers such as GAME.

The only real option to get all benefits I can see is to sub to Premier for early access and unlocks, then go to GAME for standard edition as they are offering £10 off straight away AND £5 back as I am elite member. That drops standard to £40 total...

The question many friends keep asking however is how these Origin Access unlocks actually work?

Will they be retracted on completion of the subscription? Are they tied to the account once purchased in full? Do we still get the 20 Airlift items after a month? What about those special Assignments after a month?

I find EA very hard to find accurate information, moreso with their history and even more so with the vagueness of the Origin Access T&C's.

I would rather not pay £15 for only 1 months access when I could drop 5 days early access, but pickup deluxe upgrade for lifetime benefits if indeed not permanent from Origin Access.

Way too many If,Buts and maybes >.<

Thank you.
