You're going to pay either way. Slapping new tariffs on goods or raising tariffs on existing tariffed goods gives the green light for domestic producers to raise prices as well rather than risk leaving money on the table.
You have a $10 item that tariffs took to $15. Great. Don't buy it. Now the domestic producer sees he can sell his $10 item for $12 or $13. The thing is that it's not just 1 item. You buy much more than 1 item... that you're now paying 10, 20 or 30% higher for.
