Just popped into Zavvi in Leeds and noticed they've got the complete Dads Army DVD collection on clearout price for £39.99 - with 20% off at the till that made it £31.99. Great price I think for this wonderful gem of a comedy. Closest price online i can find is £43 at Amazon.
Box set contains Series 1, 3-9, the Christmas Specials, & the 3 surviving episodes from series 2. Instore only deal I believe.
