Really? You could do it for $2.50? You should start your own shipping business then. Ever shipped something to say Argentina?
You can get blank CDs and manufacture a ready to use software package on that CD for 10 cents?
What shipping service do you use to get a package from the United States to say Germany for $1.00? 
It only takes you less than 300 seconds to "burn" the CD, put it in a DVD case, put the label on the CD and the DVD case, put it in a mailing package, process the user's name and address, print it out, put it on there?  That's amazing. And then the time to take these to your $1.00 per unit shipping place takes no time at all?
Clearly you should start your own software shipping business. We'd be your first customer. Because for us, it takes considerably longer to do the above. And shipping overseas costs several dollars. We also haven't found anywhere providing burned CDs for nearly as cheap you seem to.
Seriously, if you think $5 shipping is "too much" plus $5 media creation/packaging/processing then by all means, don't get the CD ROM image.
Hippie, et all. You did NOT pay for a CD-ROM.  You bought Object Desktop at whatever point and you received that software.  We are simply providing a way for existing users to get it on CD now.  Since we're not set up to do massive shipping, there is some overhead.
But $5 to $10 (which is the shipping/handling part) is perfectly reasonable. It's only $5 if you're in North America. Overseas it varies dramatically. So we charge a flat $10 to keep it simple. If you don't need/want the CD then don't get it. You don't need a CD to run Object Desktop. But some people do like to have a CD archive of it.
