I've used this site for over 5 years and have nothing but good things to say about them. I've received shipment within 3 business days every time. Currently shipping is free with every order over $75. Expires 8/1.
I use them from time to time, service has always been very good but often they don't carry the top name brands. I like Kents carbon and its the only place I found that its available in the large pail size.
