> Actually it's 'Aldis', because we're talking about more than one.
Just to clarify why this is wrong. First we are not talking about more than one, there is only one "Aldi" company.
We don't use Aldi's (notice the use of the ' for possessive after a single noun) in this case even though every company name is a proper noun which would follow this rule. It's not used because the Price Map is not belonging to Aldi, it is a price map "FOR" Aldi.
We are talking about multiple Aldi stores. I don't know if Aldi US is one company, or a franchise, or something in between. But I'm pretty certain they have more than one store.
