My first time experience with JMAC. I was looking for a specific item that I had to have by the next day. They found the item, shipped it out overnight and I had it by noon the next day. I must admit when customer service took my number and said that they would contact me once they were certain they could send the item, I had very little expectation of receiving a return call. True to their word, I was called a short while later with everything in place and ready for payment. I am very impressed!! I will be using them again! Thank you for making my job easier!
