I'm not sure, but shouldn't be too much. Maybe $20-$30AUD. Well, you have to check with your other mats to see if theres any green in the threads. If there is then it's the darker red mat you need. Otherwise Light RED is harder to find and more expensive. People wouldn't sell it individually. I can because I have an uncomplete set. If you want, I can sell you a complete set of the Dark RED for $320AUD delivered.
