How can I see the offer I removed
I don’t know of any way unless you still have the page open and use the back button on your browser. I’ve removed them by accident as well and while they are still in cache, you can find them, but that’s it. There may be a way to go into your actual cache/cookies/history folders and find ways to go back to old pages but if it can be done, I’ve forgotten how. You can try to search for ways to bring up cached/history pages in Google. Good luck.
