I think Soundwarp was obsessively looking for GIJoe DVDs some time ago, but couldn't find any... But I saw today in 2 stores (JB and Kmart), a DVD boxset containing 11 hours of the 80s GIJoe cartoon. That would equate to about 33 episodes - is that all that was produced? Because there didn't seem to be anything on the packaging to suggest it was Volume 1, or that it was the complete series.
It is priced at $42 at Kmart, so should be about that elsewhere.
Also note that it is listed as a limited release, so get it quick in case stores have already got all the stock that is available.
