Sorry to hear that you are facing issues with our Adobe Stock services.
The images(single images) which you have mentioned above, were available previously on the Adobe Stock website at $9.99 each.
We've discontinued the single image purchase option for all the users. The smallest subscription plan which you can purchase is the 3 standard assets a month which can be cancelled at any time and does include an annual commitment.
I would suggest you to check outcredit packs offer.
Currently, the most flexible option is to buy a pack of 5 credits, which can be used to license 5 standard images any time over the next 12 months.
Also, can you please share the file IDs which is costing you $79.99 each so that we can check and let you know? It seems that the assets which you are planning to purchase(for which you observe the cost of $79.99) might be premium assets, such as videos, premium collections images or assets with Extended licenses.
