i agree, let it go. however, people always say that a domain is worth only what a buyer is willing to pay for it. that said, i see a buyer come in with an initial offer of say 250, and i think that naturally that is on the low end of what they are willing to pay. therefore the domain is actually worth a bit more to them. i mean, if the max they would pay was 250, i would expect the initial offer to be lower, perhaps $100 range.
i bring this up because i recently was offered $100 for a .com. the potential buyer informs me that he has just registered the .net and .org version, so i'm thinking, thanks for the bargaining chips pal! So i countered with a higher offer, and since have not heard back.
the point was raised in an article i recently read (linked to from somewhere here at dnf) that psychologically the problem is that the buyer does not know how low the seller is willing to settle for, and conversely the seller does not know how high the buyer is willing to pay, and more often than not, the final sale price is not as high as the buyer would have paid (nor as low as the seller would have sold)
