We signed in december for august use year and i just got the bill - need to pay by February 14th! If you're not paying straight from bank you have to pay lump sum - we can't pay from bank over in uk, so have to pay lump sum every year! I hate receiving those statements after christmas.
The good news is, if you managed to get 2005 points, you won't pay dues on them. We bought mid dec, so will only pay half a months dues on those 2005 points but unfortunately, a full year for 2006!
