Pickup or Deliver Something

I will go to any market and buy energy drinks that I think are useful and I will take a picture for you

You want to find out which energy drink brands people choose to drink in İstanbul, Turkey. I will go to a grocery store and buy energy drinks for each brand and send you the pictures. It is a simple task.

i can make it immediately. but why will i buy them to send their pictures to you ? i am just confused at this point..
