How badly do you need Sex? On Nov. 1, HBO Video will "street" a mammoth, 20-disc collector's set of Sex and the City: The Complete Series, all for the low, low retail price of $299.95. The comprehensive compilation, which includes all 94 episodes from Sex's six seasons and a brand-new disc of extras, comes packaged in an "ultrasuede" box (Scotchgarded, I have to assume).
