All you have to do is get a buddy that has premium and do a license transfer/make home xbox then you both have it. Thats what I did, and not afraid to admit it, Its seriously stupid how they put a time limit IMO.
You could transfer it till 7/31/14.
If you read at the bottom.
I would call ea support / talk to them and see if they can get it transferred in a special occasion. You never know, they might just do it.
I've seen them give 15% discounts max though.
