Webscraping doesnt return the expected html?

Been working on a shopping app for a while(which is working), and are now looking to expand the features, however my understanding of website element/file hierakis etc is lackluster to say the least!

Im reading this url: https://minetilbud.dk/tilbudsaviser/aldi/1?id={E2193C06-1136-4ED7-9B66-693C3EB175FF}

What im looking for is the text part that includes "30,- per kg". However when i read the html programmicly im getting a ton of text that doesnt contain this particular wanted text.

Sorry for my poor explained question but im not really sure what im looking for here, could the text im looking for be hidden? in another file? another url?

Any tips that can help me in the right direction will be greatly appreciated!
