buying from nirvana...quick question

I am going to be shipping to the USA...when they drop the package off do they ask for a signature?

No it will be in your mailbox.

Should I buy from Nirvana, Dr. Chronic, or http://www.cannabis-seeds-bank.co.uk?

I would get them from Attitude or Seedboutique for their lower prices, I have been reading way too many posts about Dr. chronic orders gettin caught by customs.

Could u send me those sites?

Well you put attitudes link in your last post the other one is seedboutique.com .
