I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.

All of my orders have originated thru your online system and have arrived on time as advertised. Your system performs great. I can decide while ordering how I want it shipped and what cost. All things said, I find your system very easy to order thru.
