Is “商店里也没有一个面包” wrong?
也 has the meanings of &quot;also; besides; either; too&quot;

When 也 means &quot;even&quot;:


[商店里也] = [even in the stores]
[商店里也]没有一个面包 = Don't have a single bun [even in the stores]
[一个面包也] = [even a single bun]
商店里[一个面包也]没有。 = Don't have [even a single bun] in the stores


When 也 means &quot;too&quot;:


[商店里也] = [In the stores too/ also/ either]
[商店里也]没有面包 = Don't have bread [in the stores neither]
[面包也] = [bread too]
商店里[面包也]没有了 = Don't have [bread neither] in the stores

Note: using the word &quot;too&quot; imply there's other item that has been sold out
