i always went with the t shrt option, but the last time i did that my mailmen almost sent it back cuz the said i wasn't home to sign for the package, which i was.. so the next order i made from them, i went with the no guarentee order as i didn't want to have any problems with me not being home.. got order fine.. made another order and again tried the no gaurentee.. never got the order, no letter from customs, nada..
just made another order about ten days or two weeks ago and went with the backpack option as the dumb t shirts never seem to fit me worth a crap.. got the order on thursday..
from now on, i will always go with the added security of paying the extra cash to make sure i get it, that way if customs snags it, or it just gets lost in the mail again, the tude will just reship it... money well spent imho..
