Well it's correct once in the title, incorrect another time in the title, and the data may be incorrect. I suspect that was a malicious attempt by the seller to be borderline on correctness, get unsuspecting sales, and then claim correct listing based on the title. Unfortunately on Amazon/AliExpress/etc this is fairly common and something that needs to be accounted for in usage of the data like this.

Yeah that's a good catch. That entry probably showed up overnight - I'm still working on the rarer edgecases. I actually assumed everything would be denominated in GB! My bad.

Edit: odd, they all show as available to me (in the US?).

Ah you're right. Some show as on sale in the US, shippable to the UK, some show as on sale in the US but not shippable to the UK, and some show as not on sale at all regardless of country (but when switching country to the US are on sale). Strange!

Stretch goal is to split up the site by geography the way diskprices does. That would probably fix what you’re seeing. But that would double the resource requirements on the backend and I’d have to rewrite/abstract a bunch of stuff…so for now I’m just going to make the pages open in new tabs, and figure we just keep looking until we find what’s available locally. Pretty sure I’m pulling worldwide, so there’s likely stuff not available in the US too.
