I wish to configure VirtueMart. I simply need to configure three things:

  1. Disable email validation when checkout
  2. Add 8% shipping cost to any or all items
  3. Add 8.25% taxes to condition of Texas

how do i do this.(in administrator panel, not coding)

Many of these are built-in establishing either VM or Joomla.

  1. To disable email confirmation, within the Joomla admin visit Site > global configuration > user configurations > New User Account Activation set to No

  2. In VM, Store menu > Shipping Module List > Flex > Configure Ship Method > choose amount for use for shipping costs

  3. In VM, Tax menu > List Tax Rates > USA > change condition and tax percentage for your needs.
