The Martial Source (martialsource.com) was a website that sold kata videos for Seito Shito-Ryu Karate and also a number of weapons kata videos. I ordered DVDs from them a few times and was always pleased with their service and with the product I received.
The site was up and open for business a couple of months ago, but when I checked last night it said “The Martial Source is permanently closed for business.”
There is a link to Ebay for buying John Sells’ book Unante, which is about the history of karate. I could not find anywhere on the site or on the linked Pacific Karate-Do Institute where a person could continue to buy the various kata DVDs which The Martial Source used to sell.
Very sad. 😦
