Year in and year out - your staff is excellent, attentive, and spectacular. My last order I forgot an item, and called in to have it added. Sure enough there it is in the box, just as requested. Customer service is always fantastic. Keep up the good work!

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
