If you're querying the IRS for tax rates every time you run a calculation, you're doing it wrong.

If you're querying the IRS for tax rates every time you run a calculation, you're doing it wrong.
- scarface74 8y agoIf you aren’t querying exchange rates often - you’re also doing it wrong....
- ralph84 8y agoDepends on what you're using the exchange rates for. The rates used by Visa only change once per day, as an example.
- scarface74 8y agoAnd you still wouldn’t store that locally. You may cache it locally - something you could also practically do with lambda.
- ralph84 8y agoWell yes, the parent we're replying to was talking about caching.
