I think everyone understands your frustration, but this certainly isn't a "Buyer Beware" scenario.
Because of how quickly you jumped to vowing to never buy from PowerMax again, I would assume that this was the first time you ordered something from them. If that is the case, you need to understand that all companies make mistakes. I'm sure you've heard of B&H Photo/Video, as they're one of the most reputable computer/camera/video stores in the world. I've ordered tons of gear from B&H without any problems. One time, they even contacted a UPS driver for me when I missed him at my house by about five minutes (my delivery needed a signature) and I was able to meet up with him in a Baskin Robbins parking lot to get my gear.
Anyway, after dozens of B&H orders over the past five or six years, I finally got my first letdown back in January. I ordered a 17" MacBook Pro and it came with a broken optical drive. Now, if that sort of thing had happened with my first B&H order, I'm sure I would have been as frustrated as you are. But back when I placed my first order with B&H, I knew that they were a reputable company and that they process thousands of successful orders every day, so I wouldn't have freaked out and posted Buyer Beware threads.
The point is, you're one customer out of thousands upon thousands. It sucks that this happened to you, but that doesn't mean you were dealing with a terrible company.
Oh, and one more thing...
You said this at some point in this thread: "I really needed to have my case last week when I was supposed to get it."
1. If you "really needed" to have your case last week when you were supposed to get it, why didn't you call PowerMax when it wasn't delivered in 2-4 days?
2. Does anyone ever "really need" an iPod touch, let alone a case for it?
