Not supporting bulk pricing

Bulk / tiered discounts is a very important component to my website

for example: https://www.munchmakers.com/product/custom-matte-coated-grinder/

The currency converter is only converting the first price and not the tiered pricing

So someone can order multiple units at a very low rate because it using the USD rate converted 1:1 instead of the exchange rate. This is only for bulk discounts
