38	* Unlike WOOCS/CURCY/WCCS, WCML does not filter "woocommerce_product_get_price" for regular
39	* products — it converts by filtering "get_post_metadata" for the _price meta
40	* (WCML_Multi_Currency_Prices::product_price_filter). A price written to the product object
41	* with set_price() therefore never passes through WCML's conversion.
42	*
43	* So the tiered price must reach the cart already converted, which is exactly what the
44	* "price_by_rules" filter above does (it runs in the "view" context, including for the cart).
45	* Handing the cart a raw "edit" context price instead would leave it unconverted — that was
46	* the 7.1.3 regression where cart prices ignored exchange rates.
