What should you google to find out about how people with goods/services are handling instability in currency value? Even if a vendor updated pricing indexed to the dollar regularly (which is not desirable at all) it's seems like it would still be hard to manage keeping any cash reserves of a currency that is not a stable store of value. I'd be interested to read about what vendors are doing to deal with this.
