I've been using it for a little while now, and it is great for picking up cards that are a bit tricky to find. Just know you're putting a bit of faith into the postal service to make sure your enevelope(s) get to their recipient. If you have some trade fodder you're itching to get rid of, I'd definitely recommend giving it a shot.
I started using it last october/november and it's the best thing that's ever happened to my collection. Unloading my edh, casual, and defunct deck fodder has allowed me to greatly increase the overall quality and value of my cubes.
It takes time, patience, and luck to use the system, but if you have a job or schedule that affords you time to check in with the site throughout the day, it can be a very profitable.
I got message from other mod saying there are discussion about this in the market street forum. If you want more info, it might be better to head there.
I have been using it for a year now and it's a great way to pick up hard to find or high value cards that aren't available in your area - especially if you have a small playgroup or live in a small city (like I do).
