I will cancel because of this. $5/month is enough to make me cancel when that is 50% of the original cost. It's an extra $60/year which isn't a ton but could be spent elsewhere.
I wasn't even sure if it was worth $10/month, so this is an easy decision for me. I liked the streaming a lot at first until I ran out of shows to watch due to the limited selection. I can use Redbox for DVDs and it will be cheaper. As stated before, the streaming selection isn't great.
