I ordered a camera from Argos. I picked up the order from a drop off at Sainsburys and took it home. The item in the box had been replaced with a cheap USB charger of similar size and weight and the box had been sealed up. I rang up Argos and they wanted nothing to do with it. Absolutely disgusting customer service and a fraudulent transaction they want to wash their hands of. Either they don't check their returns or they have thieves somewhere in the distribution system. Either way it's not great. And if something goes wrong they will do nothing to help you.
Argos will never again get a penny from me. Save yourself from a similar experience.
