Pay in cash. Convenience has its penalties.
I use my AMEX for the sky miles. Over the years we have gone to Hawaii (3 x’s), Japan, Costa Rica, Niagara Falls, Chicago & St. Martin (2x’s) for between $5 and $60 (foreign tax) per round trip.
Paying in cash enables tax evasion and payment ‘under the table.’ Real tax reform won’t happen until enough voters feel the wrath of the onerous tax burden.
