Spotted this in the ASDA sale on their website. Great price for a full HD 42" TV!
Can get this for £346.84 after Quidco discount as well!
Edit: As someone mentioned, I don't know if this is available at this price in-store. Standard delivery price is £4.95, or you can select a convenient delivery date at the checkout for this product. Delivery charge £5.95 (unless Islands/N Ireland £9.90 which are delivered in 2-5 working days).
