I think that, tig, you are missing the point. Which is: it's a hobby, part of the game. Taking 'em back to the store, selling 'em on Ebay, having more than will fit in your machine (look at the sigs) is like collecting and trading baseball cards and model train stuff.
Now, let's look at the flawed analogy of returning an automobile to the store. It's against the law! The minute you drive it across the sideway and off the dealer's property, it's yours and forever. Now if the law were otherwise that would compel dealers to accept returns for full cash refund within 30 days, what percentage do you think would be returned?
10-4, good buddy, over and out.
