What’s the average price people are paying?

I’m not looking for sources or anything at all to that extent. I’m just curious 350 USD is the current going rate for 2 grams of SR-17018 or if that is too much. I’m currently on 4mgs of methadone but I do recreationally abuse dilaudid about twice a week. I want to end all this because it is affecting my mental health pretty much feeling a high for two days and suffering it through for five days. It is unsustainable long term and I’m feeling discouraged and depressed about my ongoing situation. Although I piss clean on clinic day I know I’m lying to myself and everyone around me for a subpar two day a week binge. It is no longer worth it and the 4mgs of methadone won’t hold me over because of the strong bind dilaudid has on my opiate receptors. By the time it’s Dr day again I’m practically in a moderate-major withdrawal sneezing fits, loose stools, runny nose consistently. If anyone has any advice as well any is appreciated. I’m located in Canada not US so things regarding methadone and harm reduction are little different over here.
