18 Steps to Fluency in Glosa

I’m surprised to only find a snail mail address to the UK from which to pu= rchase “18 Steps to Fluency in Glosa.” Please, don’t tell me that, in this= modern age, I have to send a paper check via the postal service across th= e pond to acquire the material necessary to properly learn Glosa.

I’ve b= een searching the web for something better to learn, and even tinkering wi= th my own conlang, but the only auxlang that won’t get out of my head is G= losa!

What books do I need to buy to learn Glosa, and from where?

Thank= you.
