Home Depot emailed receipts

This one is fairly specific. I save receipts when I get them via email usually from my phone. But no matter what I do, I can’t save receipts emailed from Home Depot. On my Mac, there is a PDF of the receipt at the bottom, on my iPhone, there is not (it really doesn’t make sense to me). Is there a way anyone has found that you can save the PDF from iOS? I would be willing to forward someone on of my re riots as an example if they would like to see it.
