Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.

Have placed many orders in the past months with sales representative Brittany Cornish and couldn't be more pleased ! She is always a joy to speak with, and she always makes sure that my orders are delivered on time. She's a great asset to your team but I'm sure you already know that.
