man, I hate to sound the cynical scrooge here but why don't you wait and see what the shipping charges are first, if the carges are even listed. Your item is a pretty standard size and weight item and $10 is a big difference as far as minimal shipping charges go. But then again we're talking $10.
I have a guy that wants me to send him $520 to his "son in England" for 3 Buck Rogers snare stands that I have never even seen a picture of and he doesn't understand why I have a problem with this potential transaction.
Why would I "trust" this person I have never met to be straight up?
I have very definately learned that the drumming community is a very small and tight group and I make sure that my end is straight forward, but I have also learned that the other end is not always concerned about this tight community. If the charges really are higher, is that your fault? I'm sure you would have gladly paid $10 more had that cost been presented on the onset.
If I tell you I will roof your house for $6,000.00...great price, and into the job I say I need another $1,200 for material I didn't know I needed, what would you do? Not everyone is honest...............................
