At some places I've worked, we still get a quote anyway. This may come as a shock to the purchasing team, maybe not, but it's always come back with the price on the website. Just the SOP for us I guess
You have to show the bean counters the quotes/bids you received and justify why one was used over the other when the cheapest option wasn't used. You can't put "price on the website" into the bean counter's files.
