I was going to do this last week after a PWE showed up. Then 3 more followed and I figured I'd better wait a couple more days to see if anything else arrived. It's been a couple days, so I now feel safe.
And there's 4 PWEs worth of cards. I know I've sent at least one bubbler off recently, but there should be another on its way to Portland shortly. You already know two of the cards that will be in it, so hopefully the others are a nice surprise.
