I calculate that as a 12.5% savings out the door.
Which means you spent 12.5% less in taxes needed by poor people to overcome the plight of being born into a racist, imperialist, greedy nation like the US.
You spent 12.5% less on in-store wages.
You spent 12.5% less on manufacturing jobs.
You're no morally better than the 1%ers who ship jobs overseas to maximize their profits.
Saving money is self-centered economic treason.
