> If you want to use GeoIP, fine — but only for currency, shipping, legal stuff
Possibly not even then. Shipping should depend on the address it's shipped to, not the IP. Currency, I prefer in your original currency. I don't want you to convert currency for me, because my bank does it cheaper.
And of course geoIP can be wrong because of VPNs. Only use it when other methods like user preference and `Accept-Language` or similar have failed, and make it easy for the user to correct your wrong assumptions.

Sure, but it's nice to show predicted shipping costs before the user has had a chance to choose the address. As long as it's clear about what country its using and properly updates when you correct that it's OK to use GeoIP for this.
Agree on the currency - you could make it an option (have seen this on some ATMs for withdrawals) but no idea why anyone would not want to defer the conversion.
