About Offers:
Please, when using the "Make Offer" feature, be reasonable.
Offers of half or a quarter or 1% of the asking price really just
waste your time and ours.
Even if an item does not say "Make Offer" we may consider offers that
are close to the asking price.
FOR non-USA BUYERS:
Paypal requires that we obtain a signature from the customer at
time of delivery. If your country's postal service does not have a
method to return a signature to us, then we cannot accept paypal
payments for postal shipments.
We are not responsible for:
Customs
duties,
Customs
seizures,
Damage caused
by customs agents.
We can not falsify any
customs
documents, this is a serious crime in the USA.
Many countries limit the
insurance available on postal packages. In this case we are not
responsible for any lost value above the insured amount.
If your country has postal
restrictions on valuable items or cannot provide a signed
proof-of-delivery, we can ship Fedex, but you must provide a Fedex
account number for shipping and customs charges.
A note about ebay's DSRs, better known
as "stars":
Ebay does not seem to offer any
explanation of the "star" rating system to buyers, so we'd like to say
this: Leaving anything less than a five star rating is just like
leaving a negative feedback, or maybe worse.
If a seller has any one of the
four sets of stars fall below 4.3, ebay will automatically ban them.
(At least this is what ebay told us during summer 2008.)
Since these ratings are anonymous, sellers cannot respond to bad
ratings, in fact we are left wondering why someone left us less than
five stars:
Did we get dinged because the post office delayed a package?
Did the buyer expect some option that was not included?
Did we offer perfect service, but the buyer just figured that 4 stars
means excellent, five is reserved for miracles?
Since the star rating
only
covers the last 12 months, our rating can change without receiving any
new feedback as old ratings cease to count. So again, when we see a 5.0
become a 4.9 we're left wondering if that was really a response to a
recent transaction, or just a 5 star rating from a year ago
disappearing.
So we ask our buyers: PLEASE, if
you don't think we deserve 5 stars, send us a note and tell us why. If
we can do something after the fact to earn a top rating we'll try to.
If not, at least we know why we are being down-rated.
