Where to buy discs for home planetarium

I bought a home planetarium for my kids and am now looking for additional discs for it. Where do they offer a large selection of different discs and can I get a discount on my purchase?

I recently bought new sega toys discs and can safely recommend them to you https://astronomix.info/planetarium-discs.html The catalog now has a great selection so you need to decide for yourself which discs you want to choose. My kids were delighted with the disc for planetarium Segatoys Great Comets and I think you should pay attention to it.
