CASIO Code Checks, Day by Day
Every CASIO code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many casio.com would not accept. That is the checkout testing you did not have to sit through yourself.

What These Numbers Mean
A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means casio.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:
- It expired or the store switched it off after it was published.
- It was single-use and had already been redeemed.
- It only covers certain categories, brands or individual products.
- The cart did not reach a minimum spend.
- It is limited to new customers, a first order, or an email sign-up.
- It cannot be combined with an active sale or another code.
- It is tied to a different country, currency or membership.
So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily CASIO discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.
When CASIO Runs Sales
Recurring events worth timing an order around. Windows shift year to year, so treat them as a shopping calendar rather than a fixed date.

- late December to JanuaryEnd of Season Clearance

When Do New CASIO Deals Drop?
Our agents log every new CASIO promo code and deal the day it goes live, and record what the working ones took off a real cart. Here's how many landed each month over the past year, how deep the discounts ran, and when it pays to wait.

Before You Buy at CASIO
What shoppers ask most about CASIO.
›Which product lines are excluded from promotional discount codes?
Promotional codes and military or first responder discounts exclude all items priced over $999.99, sale merchandise, and outlet products. For instance, high-end MR-G watches and selected limited-edition releases never qualify for coupon code applications.
›Can I combine multiple coupon codes on a single order?
No, promotional codes cannot be stacked or combined with any other active offers or site-wide sales. Each transaction is strictly limited to a single discount code per checkout session.
›How often can I use my ID.me military or medical discount code?
Verified military members, first responders, and medical professionals are limited to receiving one single-use promo code per calendar month through ID.me. If you return an item purchased with the code, the code itself cannot be reactivated or reused.
›What happens to accumulated G-SHOCK points if I return a product?
Points earned from the returned purchase will be deducted from your G-SHOCK Points account balance upon completion of the refund. Additionally, any merchandise acquired strictly through point redemptions is considered final sale and ineligible for return.
How We Verify CASIO Codes
Nothing goes up here on trust. A CASIO code is collected, applied to a real casio.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.
