Walmart sells them nationwide I believe, and yes, they really do smell like bourbon when they are in the bag. It is actually quite strong from the bags I've bought, and the flavor that they give is really really good. Here is a link to the Walmart site to see if they are in stock local to you -

I will say that I have used a bourbon marinade and it was really, really good. It used bourbon and honey and provided a great steak and sauce from the reduced leftover marinade. I think next time I make it though I am going to use brown sugar for that caramelized molasses flavor. I think it will be even better that way. This marinade is also good added to sautéed mushrooms. Just put a little in the pan to deglaze them when they start to brown.
This is a pretty sweet steak though, so you may want to cut back on the sweetener or cut the sweetness with some veggies sautéed or grilled with a vinegary marinade. Here is the recipe I have used -
Bourbon Marinade Recipe
-1/3 cup bottled steak sauce - like A1 Sauce
-1/3 cup bourbon
-2 tablespoon honey/brown sugar
-Freshly ground black pepper to taste
-Optional -1 teaspoon of cajun seasoning, i.e. Chef Paul Prudhommes or Zatarain's. If omitting, replace with slightly less salt to taste.
-Freshly minced garlic. Garlic goes very well with the bourbon though, so I always add a little.
Marinade steak for at least 2 hours or overnight. Remove steaks from marinade and reserve some for basting steaks while cooking and rest for reducing a sauce. Add a red wine vinegar to the sauce for the reduction if a more tangy flavor is desired, or even add dijon mustard for a sauce that has a bit more body.
Good luck though and post how you like the marinade if you ever happen to try it!
