What do you think the red flags are?

I have student prime and it only costs me $40CAD/year for prime music, video, and shipping. It's way cheaper than literally any other streaming service I have.

I use the Libby app and check out ebooks from my local library usually. I have a bunch of physical books as well, but I am out of room to put them now. I also find ebooks to be more convenient. I can read whenever I want because I have all the books I'm reading on my phone.
