<prompt> Human: Is it only restricted to real estate? For example, SF Bay Area houses being much more expensive than houses in Texas. My point is, even if other day-to-day stuff is more expensive in a certain area, whats stopping someone from just ordering everything they need online? Unless online retailers charge differently based on where the goods are being shipped to?  <response>: I would guess less than 10 of my spending can be done online. Education, gas, utilties, taxes, groceries, and medical expenses all come to mind as things youre stuck paying local prices for.
