What's the difference between "im dem Laden" and "im Laden"? Is it a matter of emphasis?
'im dem Laden' is wrong. You probably meant 'In dem Laden'. 'Im' is a contraction of 'in'+'dem'.
whats the diffrence in the meaning between saying im laden and in das laden?
just in the bedeutung.
im Laden (inside the store) is Dativ, while in das Laden is Akkusativ (into the store)
Why wouldn't "at the store" be correct?
If you are at the store, you are not necessarily inside the store.
Why "Inside the drawers" is not correct?
"Drawers" appears to be a regional and/or Austrian usage of "Laden".
Would "in dem Laden" mean the same thing as "im Laden"?
Why in dem?? Why not im directly??
You could use "im".
