What time of day is best to work the market? Also, any tips on flipping would be greatly appreciated.
I often flip cards on my laptop after dinner for an hour or two (7-9pm EST) while watching TV with my wife. I'll have 5-10 tabs open with different cards, and they usually move as fast as I can create orders. That's when I make most of my stubs each day.
I've also noticed cards are cheaper in the morning than at night. Sometimes I put in "lowball" offers before going to bed that are well below the current going rate, only to be surprised by the fact that I got a couple when I wake up. When the price goes back up in the afternoon/evening I've made a solid profit.
