On: Ask HN: Someone is offering to buy my side project

[petervandijck]

If they don't want to make an offer, say you'll consider offers 30K or higher, and mention that with this offer, you've started looking for buyers.

Negotiate down to 10K if needed (but don't say that).

Don't go below 10K (it would cost them that to build it, and they'd have 0 users and 0 incoming links).
