Change a discount on my NameMaxi domains

As you know, on some of my domains I set a NameMaxi lander. In my NameMaxi account I can set a discount. Earlier I set a 10% discount. Today I increased it to 25% as a test.

For example, my jewellery domain CitrineRing.com 

Price on the marketplaces like Sedo and Afternic is $3999 but directly via Escrow.com ( see Seller on the top) is $2999. 25% discount off or $1000 off.
