i dont buy as much records from the net anymore. it has to be something i can't find or something i have been wanting for some time now,plus it has too be from a dealer that i have dealt with before, i got some dealers i deal with all the time.
as far as once the weather has cooled down, i dont know about that,water get to the package and your screwed you realy have a warped cover inless you buy new , but i dont buy any neew records.
basicaly you just have to tell them to pack them realy good is all, they give you a place to add comments when you purchase just write it there

LEASPACK RECORD WELL SO IT WONT WARP OR GET WET IF LEFT OUT SIDE,USE DOUBLE CARDBOARD.
my post man is great at delivering my records i get them in great shape except if they get fuct from the other end.
