I have been selling on eBay for some time now and see an unwelcome trend involving "less-than-honest" sellers (Power sellers included) that, as a rule, not the exception, charge outlandish money to ship their items.  There have been auctions I have seen recently where the seller is charging a "flat rate" shipping charge to the U.S. of $157.00 to ship a 30lb motorcycle transmission...that's right $157.00!  To ship ANYPLACE in the U.S. would be a MAXIMUM of $50.00 -- insurance included.  This is for a USED part.  I, as a seller, know that there is cost involved with consumables such as tape, bubble wrap, boxes and such; but I find it hard to believe those items would tally up to $100.00!  I ENCOURAGE you to use the SHIPPING CALCULATOR if it is offered.  If the charge seems excessive to you, it probably is.  I understand that sometimes mistakes are made.  In this case, use CONTACT THE SELLER on the auction page to confirm shipping charges.  I did this on the above auction; and, of course, I received no response.  BEWARE!  Sometimes we see an item we MUST have, only to find out that after winning the auction, the shipping charges are more than the item's worth.  KEEP YOUR EYES OPEN.  If there is any question in your mind about actual costs, you can get weight and size information from the seller and use the FREE tools @ USPS or UPS to figure shipping charges.  I am sorry to see this happening.  These folks make it harder for the good guys. I NEVER overcharge for shipping...it's not good for business.
