The parent comment states "I bought a pan that arrived with a small defect". Under UK law, that would entitle him to a refund of product cost, delivery costs, and return costs (and Amazon's policies go further - even if not faulty, the seller must provide a UK returns address or pay the costs).

He didn't say anything about a defect. The pan arrived and he didn't like it. I don't think that's the same situation as a defect.

https://news.ycombinator.com/item?id=14911971 clearly mentions a defect. The parent post of that post matches your description though.

Oh, I was looking at the wrong parent.

If that's the law then yes?

Show me such a law.

All EU member states have laws implementing http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex:319... (non-conforming products have to be fixed/replaced free of charge) and http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:320... (consumers can withdraw from most distance contracts for 14 days (although here they have to ship back on your their costs))

Here you go:

"I bought something sight unseen and now I don't like it, waah" will indeed entitle you to a full refund within 14 days under most circumstances.
