// * DisplayNotice: true/false, controls whether the user is provided  ||
//   with a popup letting them know their product is added to the cart ||
// * DisplayShippingColumn: true/false, controls whether the managecart||
//   and checkout pages display shipping cost column.                  ||

//   and checkout pages display shipping cost total row.               ||

//   rate was 7.5%, you would set TaxRate = 0.075                      ||
// * MonetarySymbol: string, the symbol which represents dollars/euro, ||
//   in your locale.                                                   ||
