Promo code questions

Where do I enter my The Exhaust Warehouse promo code?

In the promo or discount code box at the exhaustwarehouse.com checkout. Copy the code from this page first.

Why isn’t my The Exhaust Warehouse code working?

The codes here list no minimum or item limit, so check you pasted the whole code. If it still fails, try the next one.
