MillerCoors used to sell Coors Light Home Draft and Miller Light Home Draft "kegs" at my local grocery store, but I have not seem them in a long time.
The reason I ask is because these units are very similar to the Tap-A-Draft, which is designed for local brewery take-home as well as for home brewers.
If you can find a way to get rid of the Miller or Coors beer, it's a much better deal to just buy the full one at the grocery store for $18, since a tap and empty bottle at the home brew store is $43 plus shipping. But alas, they have disappeared from stores in Charlotte, NC.
I think that in at least selected areas, distributors report the MillerCoors product has been discontinued. But the product still shows on the Wal-Mart site, and shows on the MillerCoors "Innovation" page.
Does anyone live near a store that still carries these?
