Three for the price of Two?

Hmm…seems like a novel idea but it looks like you would need a custom faceplate for it to work.

“Looking at the street pricing, these things once cost $15 to $20, but you can snag either 15A or 20A triplex receptacles on Amazon for $5 plus free shipping on orders over $25.  Wall plates aren’t included.”
