I really like how your program turned out. In the first auction, there's an interesting anomaly. I'm sure your spreadsheet calculated the correct result, though. At bid #13, ebay allows an increase at LESS than the current bid increment. Interesting! I wonder if the bidder intended that?
Of course, I DID think of something that you could do that could be considered an enhancement.
It would be neat if you could have at the very bottom of the list a line: under bidder column if would say, "END OF AUCTION" and then have the end of auction date & time under the date & time column. Yeah, I know! -- Much easier said than done! 
I noticed you were able to post the 2nd fairly soon after the first. Did that include the processing time in between, or had you processed BOTH before posting? If it included processing time -- WAY TO GO! I'm impressed! Of course this means I won't need to do my "Once upon a time" stories anymore!
Nice job, Puppy!
