Very very best shipping. Very helpful customer service.
I order a Casio PX500 digital Piano from them, the price is very good and they shiped my piano the next day using ground shipping, gave me the track number by email.
1.5 weeks later, my piano still not arrive. I checked UPS web site and found it seems the shipping is stucking somewhere in UPS.
I then sent a mail to American Musical Supply to mentioned such situation at midnight(12am at CA), they response the email right after 5 minuts and said they'll ship another one few hours later using 2 days air shipping by their cost.
Then my piano arrived in few days later.
I don't really care about the delay of the shipping as this is not their fault, what important thing is their response time is very fast and willing to help you to solve the problem.
This store is definitely a trustable on-line store, I'll recomment it to any of my friends.
