Thanks for the report, Geoff.
It occurs to me that if I were in charge of setting up a price match system with the known Kobo inputs and results, I'd set up the submission form to fetch a copy of the web page at the submitted URL and attach it to the report. That way, it avoids the possibility of expiring deals. Attaching a copy of the Kobo invoice (via order number) would make the agent's job dirt simple - look at the two attachments, pull out a calculator, do the math, issue the credit, notify the customer. Making an intranet page for the agent's use - plug in competitor price, check a box to verify you looked at the screenshot, and submit - would bring the task down to "half-decayed zombie" complexity.
