No fair! They're using brains against us! We removed our brains to make room for guns and explosives!
They canceled one item on me (Lurker at the Threshold for Arkham Horror), but honored the free shipping even though I was no longer above the threshold. Unfortunately cancellations happen more often than I'd like - about 20%-33% of my orders wind up with a canceled item. I've literally never had a canceled item with any other online gaming store I've ordered from.
Interesting. I've never had an item cancelled, even if their on-line stock only showed a copy or two left. Had a few missing single minis but it was fixed within a week by one email.
