Ahc's label is only partially captured — rows may grow as parsing completes.

Rows come from parsed labels and live offers. Where a label isn’t fully captured, we say so instead of guessing.

The bottom line

Both lines come from the parsed labels and the prices on this page — neither product is the reference, and neither is called the better one.
