bought a sony 32 inch tv for our static caravan, when i unpacked it i realized it was a little bit on the small size, so decided to take it back and exchange it for the same model but the 40 inch version (which i was prepared to pay the £80 extra) under their 30 day refund policy that argos operate,to my horror argos would not do the exchange because i had unpacked the tv from the packaging,i am now stuck with the 32 inch tv.i will never shop at argos again,moral of this story be very careful when purchasing a tv from this shop as you wont be able to exchange it if you opt for the wrong size tv.
