It said on my end that I'm purchasing 20oz bottles but on the stores end it says a fountain drink and when I ask for the driver to make sure I'm getting the 20oz she said they don't do substitutions. Theirs barely any price difference between the two and in fact I'm paying more for the fountain one than the bottles. I have always had issues with this store and their attitudes, it's like they are doing you a favor instead of doing their job.
