Unfortunate I have to do this. Part Werks of Chicago placed an item on evilbay. The winning bid was X amount. On their listing is an additional $0.60 delivery confirmation fee and a link to calculate your shipping. Total of $Y. Paid by paypal. Checked the paypal charge later to find the charge was greater than $Y. Contacted Partwerks an spoke with "John who is incharge of shipping." Discussed the varience and agreed to credit me the difference. 10 days later, no action. Contacted "Mike who is in charge" and and agian confirmed the difference. Gave me the feeling that due to the small amount of difference it was rude of me to bring this up. Still no resolution.
Bottom line: Watch your charges and invoice from Part Werks of Chicago.
