I purchased this DVD from Martial Arts Supermarket out of NJ.They sent me a DVD that had the label "How to Spar" but the content on the DVD was "Weight training for Martial Arts".I had to return the DVD at the cost of $5 postage.I waited a few weeks with no DVD. I contacted these people again asking for either the DVD or my money back including what it cost for postage to return their mistake.I admit they did respond quickly but only payed a portion of the return postage and sent a smart mouth reply.Do yourself a favor and buy from another martial arts supplier or you'll have to deal with bad customer service.
