Hello! I had exactly the same problem a while back, so you're definitely not the only one. What helped me was sticking to websites that explain things in plain English instead of trying to sell me every offer they mention. Somewhere in the middle of my search I found
https://bet-nv.com/ and noticed they actually compare sportsbooks, explain promotions, and include useful background instead of only shouting "best deal ever." I still double-check everything before making decisions, of course, but having organized information saves a surprising amount of time. Makes the whole process way less frustrating, if you ask me.
