This is bizarre to me. Do you always shop this way? Personally I find a favourite brand and stick with it. There isn't a single product I can think of where I'll buy the same thing from multiple brands.

Two responses:
1) And by what process exactly do you find a favorite? Clairvoyance?
2) If you can have a favorite, then the different brands must have different qualities. And if different brands have different qualities, then they will be differently good for different uses.

They aren't the same thing. They're differently-prepared multi-ingredient products. They're often not even the same species of fish, because "sardine" is a general category not a species.
So once you've decided on a particular brand and variety of chips you only ever buy that single brand and variety of chips, never branching out to try different things? Never get an urge for wavy chips instead of traditional, or maybe tortilla chips the next time, maybe even every now and then cheese curls?
I don't even like Sardines but I definitely understand there's a ton of variety in flavors and packing styles and even the species of fish can be a little different.
Some people would happily eat the same thing for breakfast, dinner, and supper every single day for the rest of their lives. I don't necessarily understand it, but I've met plenty of people like that.
Shelf-stable foodstuffs like canned sardines can be ordered for delivery from the regular Amazon, the same side of their site you might order a book or a laptop from, outside of their newer grocery retail channels.
I went to my local grocery store (small West Texas town)last week and bought the last 6 remaining cans.
I've never once seen the sardine shelf empty until last week.
Here in the US, on the regular retail side of Amazon, I see a twelve pack of 3.75oz canned sardines in water, Beach Cliff brand, for $18.96, or $0.42/oz. I don't buy sardines but this seems not terribly out of line with prices I see at Walmart and Target, maybe a 20-25% premium. A local fancy grocery store has sardines in water from Chicken of the Sea at $0.58/oz.
