Cool way to get a discount, but again, unless you need to move things around a lot, or unless you just want the "cool" factor of the plugs, I would skip them.
I went round and round with myself on this same topic. I almost got them just because I thought that it would make the connections look more "professional"...
Ends up that nobody else but me looks anyway, and I get the best connection with bare wire anyway.
Another train of thought is that you definately won't hear a better sound with bananas, but unless done right (which isn't hard, but you never know) could end up with something inferior...
