Hello,

I have a few questions I would appreciate if you could help me out with:

First, I wanted to ask if "bazılarını alabilir miyim" is correct for "can I get some of them?"

Correct.

Second, there is a few phrases I would like to know how to say in Turkish:

-- While you do that, I´m going to get some laundry detergent.

Sen onu yaparken, ben biraz çamaşır deterjanı alacağım.

--It looks like we just ran out.

Öyle gözüküyor ki az önce bitmiş.

--Are you open? (As in an aisle at a grocery store)

Açık mısınız?

Teşekkür ederim!
