The Piccadilly Circus and Oxford Street (London) branches of the Zavvi chain are currently selling a selection of Network DVDs at pretty good prices. On The Buses, Bless This House, George and Mildred, Please Sir, The Goodies at LWT, Man About The House and Benny Hill are all at £7.00 or £8.00 per individual volume. They also have Catweazle volumes at £11.00. Not sure if these offers are nationwide, but might be worth a look if you're interested in any of these titles.
