A few things yes when a company approaches you then you want them to blink first and give a number.
3. "Why don't you throw out a number?" There are differing schools of thought on this, and many people believe you should never be
the first person in a negotiation to quote a price. Let the other side start the bidding, the thinking goes, and they will be forced to show their hands, which will provide you with an advantage. But some research has indicated that the result of a negotiation is often closer to what the first mover proposed than to the number the other party had in mind; the first number uttered in a negotiation (so long as it is not ridiculous) has the effect of "anchoring the conversation." And one's role in the negotiation can matter, too. In the book
Negotiation, Adam D. Galinsky of Northwestern's Kellogg School of Management and Roderick I. Swaab of INSEAD in France
write: "In our studies, we found that the final outcome of a negotiation is affected by whether the buyer or the seller makes the first offer. Specifically, when a seller makes the first offer, the final settlement price tends to be higher than when the buyer makes the first offer."

But like
@biggie said you knocked on his door to sell the vacuum cleaner, he is not going to make an offer.
Outbound marketing puts you in less of a position of negotiating power, you contacted someone they didn't know your name. You must want or maybe even need to sell.
Inbound marketing now they know your name and want what you have, better negotiating position.
You said they said NO, you need to be careful there is no potential TM play here, they might want you to quote $100,000 and then file a UDRP, you never know so be careful.
