The person didn’t choose to get shot though, while you still chose to buy the product at the higher price. That’s the difference.

Why the price went up makes no difference to you as the customer.

I get that it sucks that prices went up because of an illegal tariff, but the customer didn’t pay the tariff so they’re not entitled to a refund. The tariff was paid before you bought the product, by the business. The best you can hope for is that prices will go down, but unfortunately that’s unlikely.
