Hi guys

sorry if this thread was raised before - couldnt find it with a help of search. If it was discussed/explained - drop me a link please.

was wondering, does online casino really always face so called "bonus costs"? i noticed that in few our cases quite often casino "bonus costs" matches (or are very close to) with gross gaming which leads NGR ~ 0. As a result, if deal is RS, commission becomes ~0 too. I would not raise this question if it would be one time case but when it happens regularly/often it looks a bit odd especially when we drive many FTDs, Deposits but at the end of month NGR~0 due to very high "bonus costs".

Would appreciate detailed answer who has insider experience from online casino and/or knows if "bonus costs" are always real and how they are calculated, etc
