Not always. Before Christmas, there were three pairs of the expensive climbing shoe type and size I wanted left, at about half off. I bought one. Price went down immediately after. Price continued going down day after day until they sold out the stock, and then jumped to full price when they replenished the stock. At low point, it was less than a third of full price. I can't quite figure out what they were doing, but it's like the system didn't like having low stock so they wanted to refill but couldn't unless they sold out first.
