- (2025-06-30) Niko Kwiatkowski: This thing automatically replaced my existing discount code for some other code that was a much smaller discount and I was unable to recover my original code.
- (2025-06-25) Nicole Nichols: Great except I got a discount code, but then wanted to add more to my cart and it won't apply to the additional items. Super bummed.
- (2025-06-21) gnormagn newton: This has saved me so much money its not even funny like I order everything online for half off you might need to do a little searching but the app is worth it

- (2025-06-15) sheregenerated13: Downloaded before a purchase and it said I already had the best rate (full price) so tbd I guess. Maybe there aren't any coupons for it. I checked to make sure they don't sell your info first at least so no harm in trying.
- (2025-06-05) Shawn Thomas: hell yeah, downloaded this before i purchase, saved 30 bucks instantly.

- (2025-04-28) Jon Henhapl: Crazy! They want access to read and search all your emails when you signup with your google account. DON'T GET IT!!!!! Crazy!
- (2025-04-12) MIG J Migliore (Mig): gee a whole $1.85 I'M RICH
- (2025-02-12) Paul James: their site said they had a discount for something i wanted to buy, when I installed and checked it out, lo and behold no discount. Wasted my time! and also a sneaky way to get people to install your addon, bad!

- (2022-12-16) Travis Wieser: So far, the extension has only popped up automatically on about 50% of the sites at checkout. It didn't even pop up on Samsung's website at checkout even though I have 50+ codes available. We need an option to manually trigger the codes at checkout.

- (2022-08-17) Callista Helms: As a college student I am always looking for ways to save money. Typically I would use Honey, but Checkmate has some amazing new features and it has been saving me almost twice as much! I can not stop recommending Checkmate to everyone I know!

- (2022-08-17) Michelle Fernandez: Checkmate helped me find codes hidden deep in my inbox. It's nice having a place you can go to that houses all the discount codes you can use without the work of digging through my inbox or manually searching for them.

- (2022-08-17) Nhu Luong: Checkmate has saved me so much during my past purchases, and I'm excited to find an extension that works as powerfully (or moreso) than other shopping extensions. Seeing codes from my inbox is so useful and rewarding as well. The UI is also really cute :)

- (2022-08-16) Alexandra Burbey: It should be illegal to save this much money shopping online. I don't normally give product testimonials but this is INSANE. I bought two huge orders from Forever 21 and NastyGal and literally saved over $100 on $500+ worth of items without having to lift a finger. Never using any other saving tool again
