Limited time.

U.S. residents only, at least for the Crypto Collectibles store, outside U.S. available for many many other stores.

The full deal is actually $10 in Bitcoin in which you can spend on ANY OpenBazaar store and is a promotion being done by the OpenBazaar team, just seen them re-post about it 2 hours ago

In fact, don't spend the free $10 on my store, just go check out the other stores, I have posted cool shit you can find on OpenBazaar many times right here on Steemit (see: "Ten Geeky Items On OpenBazaar Right Now" from just a few months ago).

No referrals bullshit, no spamming, nothing like that.   I am not even sure how long the deal is going on, jump on it now.  Details are here: https://openbazaar.com/bitcoin-promotion 

Posted about it last night but want to reiterate this is a pretty damn good deal with no real requirements of you, just buy something for free!
