since i didn't get a confirmation that i won, i wrote to eprize to confirm that i won, and here's their response:
we have checked our records, and do not have your e-mail address listed as a confirmed winner. as detailed in the official rules, all winning plays are e-mailed as the page starts to load, regardless of what appears on your screen. if you had been a winner, an e-mail would have been sent to the e-mail address you used to register.
now, i can understand that in a beginning of a sweep, sometimes there are glitches, and there a many winning messages that occur mistakenly, but having played this sweep for a long time, it worked perfectly. now, at the end of the sweep, they are saying the screen was wrong. i'm not buying it.
it should also be noted that i few months back i won one of those unilever tote bags, and after a long time, i never received it, so i wrote to eprize about it, and they said that they didn't have a record of my e-mail address as a winner. don't you know, the very next day, i received the tote bag in the mail, which just proved that i was a winner, but the geniuses over in customer service at eprize said i wasn't. sure makes me wonder about this win...oh well...
