Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!

Received order very quick. I was totally impressed with how well it was prepared for shipment. While a fragile order, it arrived undamaged in any way because of the excellent packaging. Thanks.
