I saw this in my local Zavvi today and it is available online too. This is the complete boxset covering all 5 seasons of Ally McBeal. This is the cheapest I have seen this anywhere.
They have also got a load of other boxsets at cheap prices too.
Only Fools & Horses complete series 1-7 (no specials) £34.99
Sex & the City £44.99
Band of Brothers £26.99
Just thouhgt it was worth a mention.
