I did the shuffle for a couple of weeks and it worked pretty good. Went from 1000g to about 30,000, doing it maybe an hour a day. I stopped because the price of ore is the same, but the price of inferno rubies is down about 40% on my server.

You can also get the Remote app for your phone. If someone has 50 stacks of elementium ore up for a good price, you can hit one button and buy all of it, instead of click x 50. It's $3/mo though. Worth it if you post/buy a lot of stuff, just from the time you save alone.
