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.

Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive
