This is from a text about mobile phones and battery replacements.
"......Many places offer same-day repairs, as long as the battery for your device is in stock. That is, for repair places with physical locations near you.**
I can understand the second sentence, but the use of "that is," (with a comma) seemed different than regular "that is" as in the case of "That is a cat."
I looked it up and learnt that "That is," means "to be more precise", or "in other words".
But then, why does the sentence continues with "for" after "that is", when "for" is not needed?
I would think the sentence without "for" would be fine. For instance "That is, the repair places with physical locations near you".
As you can see, there is no need to use a "for", is there?
