Love Amazon Prime. My membership comes up for renewal next month and I am totally renewing.
Keep in mind that about 99.9% of time it's not Netflix or Amazon's fault for the availability and pricing of a video. Most of the time that is driven by the studios. But, I hear what you are saying. There has been so many times that I have wanted to rent a movie from Amazon and see that $3 or $4 price and say, "forget it". You would think that even with Prime membership those rental prices would be discounted. If it's a new movie I can just take a few minutes to drive up to the local Redbox (I have three within a two mile radius) and rent it for $1, and sometimes less if I have a promo code they email me every week.
You would think that with the ease and availability of streaming these days, and competition, that the rental prices would have gone down. But, again, we can blame the crooks that are the studios who own those videos.
Glad your Wii streaming worked out.
