Yes, I've been very, very, VERY lucky. Some have been "free" (via convention attendance or were surprise additions to regular orders); some have been prizes won during various contests. Alice has a good point but, for me, the debate of whether they're true "gifts" or that we wind up eventually paying for part of them through our regular purchasing (and markups) is moot. I purchase from other companies and none of them has provided me anything resembling "free" or "gift."
I forgot to mention -- the most important thing -- phenomenal customer service and fan outreach (and I believed this even before I got anything free from them). BEST in the business.
