I have been trying to figure out when they change prices and I think I have narrowed it down a little. It seems like video cards will drop in price sometime late Sunday or early Monday morning. That's a pretty big window but I need to sleep sometime. I was watching a Radeon WX 7100 that was $375 for a while because I knew it would drop. Monday morning it was $303 but out of stock. Someone else knows this drop time better than me. Other video cards have dropped during the same gap between late Sunday to Monday morning. Of course other types of parts may have their own price drop schedules.
