keep your fingers crossed that you get outbid at the last minute. Are they from the same seller? If they are, you can always send them an email and let them know you only want one. Most times they are ok.
yep - I won them both. someone else was frantically trying to outbid me but my max bid was too high before the end of auction. I have paid for it but I have emailed the other bidder to ask if she really wanted it. If she did then she can buy it from me!!
