You get what you pay for. Do you want a good print or cheap shipping? Try WHCC (you'll need an account) as I use them and find their shipping reasonable and their work awesome. Naturally, what you might think is a fair shipping cost might not be the same as mine. As a business owner, who ships to clients several times a week, I am well aware of the ever rising cost of shipping. Best of luck.
Yes, you get what you pay for. Sometimes you pay more for the same thing when you buy it from a different source. I get many staple items at WalMart which are identical to those at Publix.
The shipping costs whatever it costs the sender. What the sender then charges me is not necessarily a pure pass-through. For equal printing quality and value but significantly more reasonable shipping charges, I will go with the better overall value. This is especially true when I have a small volume of printing which thus affects the part of the total price attributable to shipping.
I find Nations to be every bit as good as Bay. If there is a difference, I don't see it. Others may disagree.
I'm not sure, but I think I used White House (WHCC) in 2017 or 2018. I don't recall anything either better or worse than my current favorite.

Yes, that it does, for me.

Well, I agree with almost all of what you said. But if I am cooking (rarely) I try to measure correctly. My wife is a far superior cook and is intuitive in using quantities. I try to substitute knowledge where my intuitive skills are second rate. Analogy ICYMI.

Thank you all for your (perhaps) accurate but trivial critiques of my simple demonstration. Let’s skip to the "thought experiment".
Let us use one lens. 100 mm prime, for example.
Let us use two cameras. For example, Sony A7Riv and A7iv
The A7Riv has a horizontal pixel count of 8448 pixels.
The a7iv has 7008.
They have the same aspect ratio.
They are both full frame sensors. The EXIF will report the same equivalent focal length for both. The angle of view is the same. The physical size of the image on the sensor is the same.
Take a picture with each of the same subject when focused at the same distance. Use infinity if you prefer. Use the same exposure and ISO.
View the pictures on the same monitor at the same screen resolution: use 100% for the A7Riv. You will need to use 8448/7008 = 120.5% to get the same on-screen image size for the A7iv.
If you want to print, then if you use the same relationship of pixels to dots for both prints the same ratio will apply.
Is it clear yet?

It’s fun getting all that arguing about simple truths.

This is a completely invalid comparison. Physical dimensions of a digital image make no sense for comparison.
Wrong. They affect ability to crop for small distant subjects.

Bingo! Then all you need is a reference, something like a standard field of view on a 24 x 36 mm piece of film is 43 degrees (I made that up) using a 50 mm lens.
Field of view equal will display larger or smaller depending on sensor size AND sensor pixels.

What looks same in VF will be different in on screen view if sensor is different. That’s the point!

You also left out the fact that the 2 cameras have different pixel counts, 20% different.
No. That is what I pointed out. It’s the main reason for the difference. I just didn’t do the numbers for you.

Jerry, the equivalent length might matter to someone who needs the longest zoom for birds (example) and is considering what camera plus lens to buy. For me, it's partly that and partly just curiosity.

Can you give me an example of when equivalent focal length needs to be that precise?
No. If you don't care then you don't.
