An analogy

Here's a thought:

Sears is giving away a box of free stuff today (not really, just read). You run up excited. You hear Sears has good stuff, this is a great chance to see what they have without blowing money you really can't spare. Or maybe you've never heard of Sears, but you're looking for a new store to buy toosl from. You finally find the box back by the stock room underneath a pile of broken down boxes. It's free, that's ok. You run home with it and open it. As you open the box, prepared to feast your eyes on an item that is supposedly quality, your nose twitches and your eyes tear up and then you peer down into the box. Did they...? Yes they did, they gave you a box of shit. On top you see a note. Holding your nose you lean in to read it and it says:

Don't complain, it was free.
