confused yet?

Side One

Side Two

Who would have guessed that these two signs were for the same item but just on different sides. Okay so now we know they are for the same item my question is if you buy two that is on the side that says $5.00 does that mean it is going to be more expensive than if you buy two from the 2 for 10? If that isn't the case then how come they had to put two different, but same, concept on either side?
