John Adams posted on his blog Confessions of an RPG Publisher on Friday that he's shutting down the Brave Halfling Online store at the end of February.
John goes into his reasons and they all make a lot of sense. I think an unspoken reason is the huge delay in getting Delving Deeper out on time as well as the delay in the print rewards from the Appendix N Kickstarter. He's gotten flak for it, and it's deserved.
When you sell in PDF and Print on Demand, your products are actually on hand, not a preorder. The fact that someone else gets to mail out your orders with POD must be huge too, as I've found just mailing out prizes from the blog is a PITA when you need to work out the horrors of the US Postal System after a full week of work.
I am tempted to get extra boxes. At 10 bucks a pop Otus and Mullen boxes, they are a decent deal and they do look great.
