I can vouch for her. I bought a lovely bracelet in suffragette colours last week and it arrived in the post a couple of days later. I guess they are all gone now and only the mugs are left.
You can ask her if she will accept a screenshot of your receipt rather than sending it directly to her. I sent mine directly to her but that's because another woman I trust told me about her, but I completely appreciate others wouldn't want to do that. Hopefully she will understand and agree to a screenshot or something.
