I need to be able to order a box paper that is thicker than normal
paper and have it shipped to a P.O. Box.  I have a P.O. Box that
fowards cheaply to me in the Caribbean.  Normal printer paper is 20 lb
and I want between 24 lb and 50 lb paper.   So far every place I have
found all use UPS to ship and can not ship to a P.O. Box.  So the
question is can you tell me a place that sells reams/boxes paper in
the 24 to 50 lb range by the box and ships to a P.O. Box?

$5 for first place and $2 tip for each additional up to $11.

PaperDirect will ship to a US P.O. Box. Their FAQ say, "We also offer
First Class Priority Mail to APOs, US Post Office facilities, Puerto
Rico, and the U.S. Virgin Islands." You'll need to check their catalog
to see if they stock the specific type of paper you need.

It when I tried to buy a ream, the form says that delivery is not
available to P.O. Boxes.  It seems that only some things can go to
P.O. boxes and not "bulk items".  I tried anyway and will see what
happens tomorrow.

It worked!

They called up and said it would cost me more to ship to a P.O. Box, 
did I really want to do that, I said yes, and they said ok.

So the only way I know how to pay you is if you post as an answer.  So
please do that.

Thanks.
