buy adobe acrobat pro-"stanalone version" for teachers (no abo)?

you can purchase here but i don't see a way to designate an education license unless your adobe id is tied to an education account, https://www.adobe.com/products/catalog.html?types=pf_252Fdesktop&types=pf_252Fmobile&types=pf_252Fweb#category=Pdf-esignatures&sort=alphabetical

you can subscribe here, https://www.adobe.com/acrobat/pricing.html

but the cost for an all apps subscription is the same:
