Quick Question About Free Trials

I go to the diamond membership free trials tab, and find myself facing these three options:

going off of this, it seems to me like I could do gold membership for a week, then platinum, then diamond before having to purchase anything, and if I can, that would be really nice. 

But if I can't I would just like to do diamond membership. Can anybody help me out with this?

I should probably state the question a bit clearly, I realize that I didn't put enough detail in the post. I am wondering if I can use each trial one by one, or if when I use a free trail, I can no longer use the free trial for the other plans.

I believe what  Six_Pack_Of_Flab is saying is : "Can i use  all 3 plans ,1 week each ,before i decide whether to pay or not" NOT caring about the difference between each ,but about prolonging usage of plans without paying.

eeeeexactly

ok here's the question as clear as possible:

Gold, Diamond, and platinum all have free trials. If I do a gold, diamond, or platinum free trial, will I not be able to do free trials for any other of the memberships?

That is not the question, the question is if I get a free trial for one of the memberships, will i still be able to get a free trial for any of the other memberships

Oh well thank goodness, that is not the question I am asking. the question is if I get a free trial for one of the memberships, will i still be able to get a free trial for any of the other memberships 

Thank you for your wonderful advice, and your help in answering my question. Comments like this really increase the quality of the thread and helps bring everyone closer to solving the problem at hand. Your beautiful words course through my soul, and I shall remember them forever. Thank you so much for this wonderful gift of words.

That's the problem.

There was nothing suggested that related to the question at hand.

All I am asking is if I were to do the week-long free trial of the Gold membership, after the week-long trial period ends, would I be able to do the platinum free trial, and after that week long period ends, would I be able to do the diamond week-long free trial.

That is still not my question lol. I'm asking if after I try diamond, and say I cancel the trial before my card gets charged. Then, I go and try a free trial for another one of the memberships (i.e. I did diamond first and then I went to go look at gold)

would I be able to still do the gold free trial, or would it be locked because I already did the trial on a different type of membership?

No, you only get a singular free trial of one week, regardless of what membership level you do in the trial.

Thank you, that is the answer I am looking for

is there any reason i got 2 free trials? i used one and it just popped up saying free trial again?
