Just to make it known for people who are easily confused about time issues, this would be midnight on Sunday night/Monday morning.
For the US, Canada, the Caribbean and Mexico, Greenwich Mean Time is:
4 hours ahead of Eastern Daylight Time - auction ends Sunday 6/17 8pm
5 hours ahead of Central Daylight Time - auction ends Sunday 6/17 7pm
6 hours ahead of Mountain Daylight Time - auction ends Sunday 6/17 6pm
7 hours ahead of Pacific Daylight Time - auction ends Sunday 6/17 5pm
Kanped, if for some reason there was some misunderstanding and this is not when you intended to end the auction, let me know and I'll correct this post.
Also, people, please be CRYSTAL CLEAR about which pack you're bidding on, since there are SEVEN auctions taking place simultaneously under this topic. With the exception of the orange Friar's Club deck, they're all in bundles - win the bundle, get them all. You can't go cherry-picking individual decks and ask to bid on them separately!
