Huge Price difference on invitations when viewed in different browsers

OK, either I'm going crazy or something is really wonky with this invitation:

When I look at it in either Chrome or Firefox the price is listed as $1.58 per invite. I think this is the correct price. BUT,
when I look at it in Edge, suddenly the price jumps to $2.21 per invite. The size, paper type & print definition are all the same. I'm at a total loss. 

It's not all invites, but this one is certainly not unique. Here are a few others with the same problem:

What on earth?

ETA: I realized that I was signed in on Edge but not on Chrome or Firefox, so I signed out on Edge and the problem went away. I then signed back in on Edge and the problem remained fixed. I have no idea what any of it means, but I'm less worried now (though still mightily confused!)

Are you logged in in each browser? Or are you anonymous with some browsers and only logged in on one? I think prices vary based on whether you are logged in. And possibly who you are logged in as. Probably where in the world too.

Yeah I think that's the issue because I'm logged in on Edge but not Chrome or Firefox. The weird part is that it was only certain invitations that showed the more expensive price not all of them. Anyhow, I logged out and logged back in, and the problem went away, so I'm not so worried about it anymore - just hoping that no potential customers are turned off by those super high prices! I do think it's really strange that only certain invitations were impacted - maybe it was ones that I had viewed at some given point in time?
