Thanks Vicki. I didn't realize they were meant to be sorted. Would it be appropriate to add comments explaining the sorting? The second stanza, in particular, is sorted by the IDs rather than lexicographically. If someone sorted it naively, they'd end up with a bigger diff than expected. It looks like a few others have escaped sorting; for instance, "Microsoft X-Box One Elite 2 pad" appears in the wrong place. If Dmitry wants to land this and then follow on with a sort + comment commit (or do that first and then rebase this on top), that would be great. I can take a stab too if that's helpful.
