How to use a Monoprice promo code at checkout

  1. Pick the offer with the highest "worked" score below — that's shopper-reported, not guesswork.
  2. Click the code to copy it. We open Monoprice in a new tab automatically.
  3. Add your items to the cart, then look for the promo / discount / gift-card box on the payment step.
  4. Paste the code and apply it before you pay — most Monoprice codes can't be added after the order is placed.
  5. If it fails, hit "Didn't work" so the next shopper sees an accurate score, then try the next code down.
