I just placed a (thankfully low) bid at a GoDaddy auction for one domain, and when I submitted it, the bid went to a different, wrong lot. The other lot was open in another tab in Google Chrome. I replicated the correct bid, and the errant bid was replicated. The poor web engineering certainly has shaken my confidence in the GoDaddy auctions platform.
GoDaddy auctions support is closed overnight for the next six hours, so no hope of immediate support. Not a problem for me to follow through on the purchase, but crazy stuff.
