Buy One Now vs. Buy IT Now?
 

If I have someone selling multiple quantities of a specific item and they have Paid for an ad to run for say 30 days, then I want a buyer to easily be able to press a Buy It option, but I do NOT want the ad automatically removed until the expiration time is up. The sold stats can be updated.

Not a part of the software at this time.

Something like that would require you to modify code pretty extensively since one would have to take into consideration the multiple quantity issue.
