my respone is this, i don't usually sell on ebay- here is why
a seller owes a buyer absolutely nothing but the product pictured.
the buyer expects gold plated service for little money, a strange dichotomy.
if every prospective buyer askes 2 questions about the item,
it prevents the seller from selling other items because his time is spent on answering questions regardless of wether he gets a sale or not.
ask yourself this question, how much time would you give to other people if the time was not compensated?
much less for an item that you may realize a $15 profit and then have to give part of that $15 to paypal and some to ebay to handle the transaction
now the seller made $8, and you'd like him to be happy about it and answer every question with a smile.
seems unfair from the sellers perspective.
in most cases the buyer will cry if he is hung with a new rope
treat the sellers like you would like to be treated.
if you are realistic, you'll rarely be disappointed.
