I assume by Request for Quotation you simply mean to contact a bunch of sellers.
The problem with contacting sellers is that it exposes me as a buyer, means I have to answer all their questions, and they forever hassle me. I’m at an early stage so I don’t really want to waste their time either. Usually they won’t quote without having your full details, email, phone, etc. They like to interview you to work out how much of a mug you are...
For the same reason I like to purchase cars using desk research and then make a swift and decisive purchase once the right one comes up.
I guess I was hoping there was something magic I’ve missed!!
If this is the only way, Maybe I need a burner phone!!
