Growler Fill up??

Party Mart on Brownsboro Rd. does but they only have 5 or 6 taps.

ValuMarket in the Highlands refills growlers and so does the liquor store on Bardstown Road and Bonnycastle.

I've wondered why a growler fill up costs more than a 6-pack of the same beer (in BBC's case).

I'm providing the bottle, I'm getting 5 1/3 beers (64 oz), and I'm getting charged more. What's the deal?

However, a growler fill is much cheaper that ordering 4 pints at the same location.

And when you get those figured out, explain bomber pricing to me.
