It's pretty annoying, though I mostly use Best Buy's discount. In fact, I only have Best Buy's discount because I bought the Fallout 4 Pipboy Edition and adding the membership gave me the discount right away and the collection + membership ended up costing LESS then just the game, so I got it for less then free. 2 years for such a small price makes it WAY better than Prime, but only for video games. I haven't had any trouble finding any games I am looking for, but I haven't been trying to buy much really obscure stuff.
I mainly only used Prime for Amiibos, but those are being removed too so... meh.
