Dealdash is having a problem with one-per-user on the 5000 bid packs and 2000 bid packs. I have been talking to support and they aren't even acknowledging the problem. It you look on the history of recent winners you will see that most of March is missing. The users that won on the dates that are missing are able to win again. This is an on going problem. I have seen many users that have won multiple time recently. Hint, if you have won before you can win again now.
