It's REALLY annoying how you have to pay for 3.5 when it's the same as 4, and 4 is free when you're on plus!!

I'm on plus, which means I don't have to pay for anything.... right? Well, not really. I have to pay double for 3.5, when I could be using 4, which is free!! It's really the only model I use, and I'd be happy to get 4 any time, but it often doesn't give me that model, so I have to pay double for 3.5 when I could be getting 4, which is the same thing as 3.5, but free. I honestly definitely wouldn't pay for 3.5 when I could get 4 for free. This whole debacle is a disaster.
