I've purchased a newer model of a broken item I currently have and had to pick it up via click and collect. They are virtually identical when looking at them and was wondering if it would be possible to switch the broken item for the newer one and then take it back to the store for a refund, stating that the item was defective?

Argos are pretty meticulous when checking returns.

Are there any Identifiable markings on the Item, such as a serial number/barcode? Also, what Is the Item?

If they accept it at the counter, would I have any issues going forward when they realise it's a different item?

If It comes to that, plead Ignorance by saying you've returned what they originally gave you.
