I think I might end up using this one if I could learn more about it:

Pros:

• Makes it easier for Steemians to exchange Steem for goods
• Could be useful for people who have trouble accessing some of the more traditional payment methods

Cons:

• Website either lacks info or doesn’t make the info very easy to find (e.g. I assume there’s an escrow system or something but I’d prefer to be able to read about it in detail)
