Currys.
I would like to buy this item. Fine, we do not hold stock and so you need to buy it on our website and collect from the store. OK, I can do that.

This item has developed a fault, I would like a replacement. But you bought it online sir and because it is not a store purchase you will need to contact the online helpdesk, arrange and DPD pickup and they will arrange it from there. But you told me in store to order online as you do not hold stock, I had to collect it from the store and yet I cannot return it to the store. No, you purchased online and so you have to deal with them. So, you are basically just a high street front for your website. Pretty much.
OK, as I am here, can I call from here, leave the item here and have the DPD pick up from here as I am not in to arrange that. Waits 45 minutes while manger looks into it. OK, that is fine, we can arrange that, DPD are picking it up in the morning.
Call from Currys on Monday morning telling me I was not there for my pick up. I went through everything that had happened and apparrrenty there was nobody in the store at 3.30 on a Friday to hand it over. Pick up re-arranged, next available date a week later.
