Durio oxleyanus is available here now and of the 2 fruits I have eaten so far, I got 5 good seeds in the first and 1 in the second. (planted 4 for myself) I love this durio and would be happy to get some seeds dispersed.
Here is a thread with the topic of Durio oxleyanus ... and a photo. It has been discussed in other threads too.
http://tropicalfruitforum.com/index.php?topic=3742.0The fruits were only around in Jan of last year, so try to order soon as the same will likely be true this year.
Seeds are 5USD each. Please order atleast 3, since it takes some time to get them packaged properly and to the post office. I pack them tightly in damp saw dust in a plastic bag with tiny perforations and immobize the seeds so that if they germinate in transit, the roots will not be broken. Take care unpacking.
I just checked the Malaysian postal system web site. It is in English and has many options for mailing a small package internationally, ranging from 15.3 MYR (about 5 USD) to 180 MYR (about 60 USD). Range reflects speed of delivery and destination with "weird" countries costing more.
Here is a link to the site to calculate postage to your home using your prefered method:
