About Protocol
protocol-lab.com shoppers land here looking for a code that actually works — that's the standard this listing is held to.
Protocol's clearance items are frequently excluded from sitewide codes, worth checking before assuming a discount applies. Protocol's promotional calendar isn't public, so this page is the practical way to track when a new code appears.
Check the terms on any code before assuming it stacks with an existing sale at Protocol.

Frequently asked questions
How do I use a Protocol promo code?
Grab the code from one of the offers above and enter it in Protocol's promo or discount box at checkout. We check codes before listing them, but stores can pull a deal without notice — if yours doesn't work, another one on this page might.
Can I use more than one code on the same order?
Not typically. Protocol's checkout, like most retailers', only accepts one code per order, so a second code won't add on top of the first.
Who verifies Protocol's codes?
Fiona Clarke, Shopping Advisor, covers Protocol for Couponarc, testing each code by hand before it goes live rather than pulling from an automated feed.

How often are Protocol codes updated?
