Hachette weekly magazine series

Does anyone know how or where I can get a subscription to the Learn & Understand Astrology weekly magazine series? I have 8,9,10 but would like to collect all of them. Or does anyone have any they would like to sell? The ones I have were found at a thrift store and I have no way to call them internationally. Any help would be appreciated.

I noticed no one has answered,
I cant help but I hope you find what you are looking for

It doesn't look like Hatchette print them any more, perhaps ebay and other similar sources will be your best bet.
