Couldn't have said it better k1cjs. OP who are you to try to "force" the guy to give you a refund because you didn't agree with the amount. You pushed the button. Like the guy said you can choose who you order from. So don't order from him again. Doesn't mean you have to stomp your feet like a 2 year old on the internet and trash the guys business. Whether he is a good or bad guy to deal with I dpn't know I've never dealt with him. You don't realize how much things like this hurt a business. Like I said good or bad. You think the guy is getting rich in selling to hams? You need an education. What's next you going to call your credit card company and get a chargeback on him? Sure that costs $50-150 out of pocket. Non refundable. You probably already did.
Sorry, 'BJM, but I agree with 'IPF. When you check 'best way' you DO leave the method up to him. Keep in mind that most internet storefronts combine picking, packing and shipping under "shipping", so you paid for the package and his time besides the cost of shipping it. If the package would have cost the shipper more, you would still only be liable--and paying for--for the $9.95 you agreed to. That is what a flat rate 'best way' shipping method means.
He could have just as well sent it parcel post--with a longer shipping time and lesser cost, but then you would probably be complaining about the length of the time it took to receive the package. He sent that small package in the fastest and best way it would take to get it to you.
As to his response to you, yes, he could have been more civil, but as your complaint was not really justified in the first place....
