I have a Jazz Bass Id like to sell, but im not sure If Id be able to sell it on here due to shipping costs. I plan to pack it in its Fender box, and pack that box inside the original Sweetwater box it came in. The problem is that this ends up with a tall box weighing 17 lbs. I live on the east coast...so if someone on the west coast wants to buy the bass...the quotes from Fedex, UPS, and USPS are all over 100 dollars. Is there a cheaper way to ship? And are the online calculators accurate?
