I've been using planet express for over a year now. Customer service is wonderful and peices are very competitive!
Out of over 50 packages mailed to me through PE only one got damaged and it was the fault of the mail company not PE. PE Worked very hard on the dispute for me and I got all my insurance money back with no issues!
I highly recommend this service! 9 times out of 10 it's cheaper sending it to PE to me then it is to directly ship to me.
