As it is illegal for a UK based company to sell DVDs directly through their website I would like to recommend you try Mail and Female, based in Amsterdam that do sell my DVDs, I hope they can be of service to you.
There are many other online shops worldwide who sell my DVDs or who can order them in, it’s just a case of finding one in your country and searching under ‘Anna Span’. If you are UK based try searching for your nearest sex shop in this database where you can search by your hometown or nearest city, most UK shops stock my DVDs, if not they can order them in fairly swiftly.
