Offers, yay or nay?

Hello, I've seen many people here saying that they hate when they favourite an item and the seller messages them with an offer. And I definitely can see how it can be annoying. So, do you think that sellers should avoid making offers entirely, or do you think there's a time frame after which you can do it? If so, what would that be? Is there also a percentage you think would be too low? For example, I have an item I posted 3 weeks ago, and four people have favourited it. The price is 35. Would it make sense to make a 25€ offer since the views aren't rising anymore? Or should I just leave it alone? Thank you
