How can you tell ??

wasnt sure where to post this question, and since the topic has to do with seeds, i figured why not here lol.

Question 1. When ordering multiple strains of seeds from sites like nirvana or attitude, how are they identified when going stealth shipping should you choose the unpack and repack method ?

Question 2. Should I even choose the option of the unpack and repack method ?

Question 3. Is attitude better than nirvana ? They seem to have a wider variety but as far as genetics go, i would like something consistent as far as phenotypes go.

I am in the U.S. so obviously I'm concerned lol

Thanks
