I have tried to redeem codes in the past that show up on several different bonus sites. The code is suppose to be a NDB, so there are no other requirements in order to use it. When I try to redeem the codes, it pops up that I am not eligible for it or have not met the requirements. When I ask the gaming support why, I am always told that it is up to the bonus site on who gets to use that code and what requirements are needed and to contact them. Here is where my confusion sets in. How can the SAME code for the SAME amount at the SAME gaming site have the SAME requirements when it is being posted on DIFFERENT sites???????
