just saying

[AAQuesada]

maybe they are running a test to see if the pull top sells better? that's all I can think of

[rotuts]

they scan the same .

production line differences.

the should be coded information indicating when and where it was produced.

old production lines never die . . .

Maybe they know people have different preferences and are trying to appeal to both?  
Unlikely, I know.  

[Duvel]

I don’t get it …

 

You separate the content from the can before eating ?! How old fashioned …

 

Think extra fibre 😎

Best guess: a sleeve of the ‘wrong’ type of top was in the stack being fed into the  machine putting them on. It happens.
