Hello there! We do not have a sample box that you would be able to buy. This is something that we would be able to bring up with our Marketing Team though! They would be able to see if this is something that we would be able to do.
We do have a coupon that you would be able to print out though! You can find the coupon here: https://www.schaer.com/en-us/a/schaer-coupon
. This coupon does print out automatically though. If your device is not connected to a printer then the coupon is not going to print out.
