Two things:
1) You have probably already asked Zazzle about accepting monero but i would urge you to try a bit more or at least find someone who is willing to accept xmr and pay them in fiat. I would really like to see my XMR being used for buying these things!
2) Any (risky) timetable about blockchain and that awesome GUI? Or maybe we can wait until Friday's chat?
There are a couple of companies waiting the do 1), we told them to wait for proper GUI and blockchain.
