Well, it looks like they expire after thirty days anyway. the only time that you may not want them to expire in thirty days is if you have a sale and the item price is going to change within those thirty days.

for instance I set my expiration date for 2006-11-30 for most of my items but google base ended up setting the expiration date on those items to 2006-11-09 which is thirty days after I posted them.
the items i entered with 2006-11-07 were sale items I wanted to expire on election day here and their expiration posted for that date...2006-11-07...which is what I wanted.

So I guess that a constant would be a thirty day expiration after the generation of the file. I'm not sure how you would grab the expiration date for specials/sale items but i'm sure you know more about that than I do.
