MANTENIMIENTO DE SISTEMA DE INCENDIO

Each item compared against purchases of the same item over the last 36 months.

1 of 3 priced lines have no baseline to compare against (at least 5 purchases of the same item over the last 36 months are needed).

The open-data unit price does not carry the article's presentation (e.g. a 250 g container vs. 1 g), which can change how this comparison reads. When we can recover it, it appears next to the article; you can always check it on the official purchase page.
