Sold as seen (further damage after purchase)

[An0therQuestion]

I need help, opinions, guidance…!

On the weekend I went to a furniture store and purchased a dressing table with drawers and a mirror attached above. The item was ex-display and although the odd nick (in places you wouldn’t see) the unit was in amazing condition and I agreed to buy the item for £106 sold as seen. The sales assistant advised she would have someone break the unit down for me to collect the following day.

When I arrived, the sales assistant (different to the day before) advised they needed to speak to me as there was some damage caused by them during the dismantle; the person dismantling the furniture dropped the mirror and it split and dented the top of the unit/dressing table causing quite considerable damage. The lady advised they would knock a further £30 off, or I could have a refund.

In between buying and collecting the new unit I had already got rid of the furniture this new item was replacing, therefore a full refund and walk away with nothing was a disappointing option and so I asked if they were able to replace the top of the unit that they had caused damage to and of so I would pay the same cost as initially agreed. I was advised this wasn’t an option as the unit was no longer in stock which is why this was being sold as ex-display. After much consideration I reluctantly agreed to the extra discount and took it home.

This morning however, I have since found out that the unit IS still available, albeit on clearance (not as ex display).

Am I bring unreasonable to call the store and ask them to replace the top of the unit one of the same units they have in stock due to the fact that the damage to this area of the unit was caused by them after I had paid and left the shop. Or have I missed my chance being as I agreed to the further discount after being told this unit was no longer available?

As per my offer yesterday, I am happy to repay the extra discount back, if the store can provide a replacement top for me as this would mean they would be providing me with an item in the same condition that I bought it in initially, and they would get the money I agreed to pay in the first place.

But if they remove A panel from a brand new item, they render that item completely unsaleable. So It's the equivalent of selling you that £250 item for £100.

The panel you want is only available as part of a flat packed unit, priced at £250. If they sold replacement panels separately, you might have a point, but obviously they don't.They didn't have a spare panel to give you, as no such things exist.

You got a really good deal, and they were completely reasonable.

I think it's unfortunately not a viable option for them to fix the item selling for $100 with parts from an item selling for $250.

If they were the same value then yes, I'd expect them to do it but I'd not expect them to devalue another item by $150 to fix my $100 item.
