Until yesterday, the issue of having to choose between vendors hadn't come up because the only thing we had booked was our venue, and we only had one choice for that. But then yesterday I booked our caterer (yay!). I was in touch with a few different companies. Mostly our conversations didn't go very far, but one other company drew up an estimate for me. Is there etiquette for informing vendors we've chosen to go in a different direction? Does it apply only if they've drawn up an estimate, or if they've held the date for you temporarily? Any advice for the best way to navigate this would be very welcome. Thank you!
