My only fear is that DNA for a high-value item will trigger a PR with Ebuyer, which I'm looking to avoid currently.

The nature of the DNA triggers a PR with almost every company a lot more often than not, even with low-mid value Items.

Do you know if Box.co.uk opens sealed returns?

Not to my knowledge.

One of the places I may want to try the SB method with (Freemans in the UK) has Apple products direct from the supplier (CS said the supplier isn't actually Apple but a varied selection of electronics suppliers), but that returns were handled by their internal team. As a hypothetical, if it gets past the internal returns team and I get a refund, but it gets sent back to the supplier, is there a risk of a rebill should they inspect? Or, do you think one would be in the green once the refund goes through?
