Branching to a new discussion,
Hi Anne,
I apologize for the troubles that you've faced on the Stock website.
I checked your account details and see the single image purchase but that option was available to few of our customer because of their single purchase history with Stock.
Starting last to last week itself, we have discontinued the single image purchase options altogether. Originally, the single image options had been discontinued last year.
You can definitely check our credit pack options here: Adobe Stock pricing and membership plan | Adobe Stock
You may also refer to Adobe Stock pricing and membership plan | Adobe Stock for more information on credit packs.
Feel free to update this thread in case of any additional questions.
Regards
Sheena
