Can Memory Maker be purchased separately from Disney?

[SpaceMtn#1]

I'm planning on buying my theme park ticket from a third party seller (Undercover Tourist). But I want to also purchase Memory Maker. It doesn't seem like Undercover tourist offers it. Does anyone know if you can buy it separately from Disney or do I have to buy my tickets from Disney if I want Memory Maker?

You can buy it in advance for $149 or if you buy it at the park it's $199.

Thanks so much for the link! I know about the price difference if you buy ahead of time but for some reason I could not find that specific page. I only could see Memory maker as a ticket option and not on it's own like that.
