Query: slow shipping

I ordered this product on 3/26/07, received a shipping date and then a revised shipping date and then another shipping date. It is currently scheduled to arrive between 4/23 and 4/30. The item was not backordered so I fail to understand why it is taking so long to get it shipped. I will admit that I complained to Amazon and received a nice letter of apology and an adjustment to my order. But that has not expedited the shipping.
