I have noticed that some people are inflating the shipping in order to try to recoup some of their perceived losses for selling on E-bay. I have shipped and have shipped both inside the continental US and abroad. I can say that an amp head costs about $60 to ship coast to coast (FL to CA). I also can say that from NY to CA that a head should be close to the same. I have noticed that small I tems that I have shipped and received from Ontario, Canada cost about double what they should. That being said, if the guy lived in CA and the amp cost double to go to Ontario, Canada then realistically your shipping should have never exceeded $130. I would think that would include any taxes if declared. I believe that your seller is trying to recoup some of his loss by hiking the shipping costs. Even having large items packaged for shipping at UPS store doesn't cost $70. The fact that you said that you won the auction for $430 shows that he is losing money. Worst case scenario, after you get the amp leave less than stellar feedback and mention the inflated shipping if he does nothing to make things realistic. Regardless, I would find out how much it cost to ship. If it comes via Post office you will see it plainly on the box. If it comes via a shipping company you can have the tracking number referenced or measure and weigh the box once you receive it then ask for a quote from them. There are too many people screwing with E-bay right now and finding ways to get over. Prime example, I have seen several amps and guitars with low starting bids and no reserve but fixed shipping costs that are way out of line. Some of them are being sold by people with decent feedback while others have terrible feedback. Personally I try not to deal with anyone that has ever had negative feedback on a sale. Though it is kind of risky, I have found that newcomers to E-bay tend to be more honest than those with longer but spotty track records. It is important to check out their ID history too. Too many changes can reveal a somewhat shady individual. The private feedback is also a bad sign. Good Luck.
