Well, the most "annoying" offers i receive from
time to time on cels of my gallery are not price
related but something like:

"Tell me the price of *this* and *this*. My
address is *this*". 
And note that my cels don't have price tags and
nowhere in the page says that the cels are for
sale (even it doesn't specifically say the
contrary). When this happens if it's possible i
direct the person to a dealer's page who offers
similar cels, and ussually the person answers with
something like "Oh, i didn't think it was so
expensive."

More "annoying" questions i receive when i list
cels with a rather high price on ebay. I have
received questions like "Why is the price so high
for a piece of acetate?" or "Why is this
particular cel so expensive when i have seen cels
of the same series go for *insert low price
here*?", or "What has this cel of special to be
worth much more than most cels on ebay?", or "Why
does this cel cost that much when i have purchased
the entire series on dvd for *insert price*?" (i
bet it's not even a legit dvd), or even people who
want to play the "expert" role and try to explain
me why the cel i have listed is not worth that
much.... These last ones are the most annoying
ones. Of course i always give them polite replies
and they never question again but i feel as i
shouldn't have to be replying to those e-mails.
