I noticed recently that my member rank went from in the 1,700's to the 2,000's and then back again into the 1,700's. This tells me that WA is having trouble retaining members. It also tells me that the WA  for a buck was not as successful as it could have been. Perhaps you should consider reducing your prices to the 2005 level this might help to keep members on board, especially when one considers that the US is still in a recession.
