This makes sense for location specific services. If you are trying to compare two hotel rooms, by so means, they should be forced to include all the taxes they require since that doesn't involve your location and is important when comparing prices. But should not be a requirement for products where I would need to pay my local tax as that would require me to enter my location and would not provide any interesting extra information between products.
