Any beers entered after it closed would have required 2 day or overnight shipping and would've cost an arm and a leg.
You're not real familiar with UPS shipping maps are you?
This map is for shipments originating from just outside of Boston

North East region closed the night of 3/29
shipping would have originated on 3/30
overnight would get it to Philly (from Boston) on 3/31
2 day would get it to Philly (from Boston) on 4/1
Deadline was 5:30 on 4/1
2 day or overnight shipping, to get it there by 5:30 on 4/1 just like the map I'm supposedly not too familiar with says
Ground shipping isn't guaranteed to arrive within the days shown on that map. I've had shipments take 3 or 4 days to get to a 2 day zone. 2day and overnight is guaranteed.
