Best Day/Time to buy off market?

[SurfinSantaCruz_XBL]

Are prices lower on weekdays than weekends? Time of day? Any pattern anyone see's to buy off the market for cheaper prices?

Madden is like clockwork with low prices on weekends and higher middle of the week. The Show seems more dependent on when content drops. Despite the huge Griffey set, Friday was a great time to buy higher end cards. However, some of the lower set pieces were inflated. I was making a killing selling golds instantly at 25k. My best luck has been to list something high late at night when there are less cards on the market. Someone gets impulsive and pulls the trigger. Same with putting in low buy orders overnight. People get desperate for coins and often sell now regardless of price.
