There are two grocery stores nearby my house  where I usually buy food. One is cheaper and is located closer, the second one is more expensive and a little further than the first one. But I like more the second one although the first one has some advantages. The point is that the second one has more choice of groceries and it  has  higher quality. I buy  bread, groats, macaroni from the first one and  from the second one I buy perishable goods, fruits and meat. I think it's clear why I do this way.

Two stores

There are two grocery stores near my home where I usually buy food. One is cheaper and is closer to my house, and the second is more <a id="_GPLITA_0" style="background-color: transparent !important; border: none !important; display: inline-block !important; text-indent: 0px !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-transform: uppercase !important; text-decoration: underline !important; vertical-align: baseline !important; width: auto !important; background-position: initial initial !important; background-repeat: initial initial !important;" title="Click to Continue > by mm1505b" href="#">expensive</a> and a little farther than the first. Even though the first is better in some ways, I like the second more, because the second has more choices and the food is of higher quality. I  usually buy bread, groats, and macaroni in the first, while I usually buy perishable goods, fruits and meat in the second. 

Your last sentence "I think it's clearly why I do in that way" is incorrect, but I don't really know what it means in the context of the rest of the paragraph. Gramatically, "I think it's clear why I do it that way" is correct, but I'm still not sure what this sentence really has to do with the rest of the paragraph or why it is needed.
