First time buying here, process was smoth and fast.

The order itself was great, exactly what I needed for a great price. The shipping however was dismal. I had paid for 2 day shipping but received it after 7 days. After contacting customer service, the issue was resolved quickly and money refunded for the shipping charge. Great CS and place to shop.

Great transaction!
