I was exploring powerpoint presentations on GraphicRiver. I clicked on a button that said Unlimited Downloads and bought a $29 subscription. When I went back to the page, surprisingly it still said buy for $15! If the $29 subscription didnt include this, why was it advertised like that?
Here is what is included with subscription plan - https://elements.envato.com/all-items
And yes, that kind of ads can be confused
