I am happy to report that the seller was very nice about it. I knew it was an honest mistake on her part and she did the right thing. Now I have to look out for sales on the Valco play pen (new)! My husband pointed out that for the $60 savings, he'd rather have a new one that is perfect and the warranty - and the sell it on ebay when we want to get rid of it. I'd be happy with a perfect used one and $60 in our pocket, but I can't manage the running around to inspect these items prior to purchase - it's just too hard with a little one.

Thanks for your advice!
