${AUCTION_DISCOUNT_CPM}

What it expands to

Seller discount expressed as a CPM.

Expands with the seller discount expressed as a CPM. Added in 2.6-202606 as the absolute-value twin of AUCTION_DISCOUNT_PCT.

What to watch for

Same warning as the percentage form: post-202606, price plus discount macros together describe the transaction; the price alone no longer does.

Encoding

When a macro rides inside another URL as a query parameter, the expanded value must survive URL parsing: exchanges support suffixed forms like ${AUCTION_DISCOUNT_CPM:B64} (base64) where documented, and values containing reserved characters must be percent-encoded. An unencoded expansion is the most common reason a notice URL truncates at the first ampersand.
