I still disagree. In certain circumstances I would (and have) walked in to a physical shop to get a replacement without the original.
To get a replacement without returning the item as you have apparently done is a rare exception. To expect this to be possible and normal from every other dealer is expecting too much and is just not going to happen. Goods having to be returned first is required in just about every case. And I've returned a lot of stuff over the years.
I've only returned one item to WE. A printer calibration thing. Not faulty - just wasn't what I had expected. After a telephone conversation they were happy to exchange it for something more suitable.
