Well Chris, I believe I just might be able to save the day!
I live in New York, and I too have been searching high and low for the elusive Sheridan's Coffee Layered Liqueur.
I was almost giving up when a friend of ours told us that he had a case of it shipped over from the UK.
Actually, he's had three cases sent by now.
He said that these people are great. The first shipping was literally crushed during transit, apparently some machine squeezed it against a wall or something. Anyway, the point was, they gave him a full refund, no fuss.
So I tried them too.
It arrived in three days from the UK, in perfect condition.
I haven't drank all six bottles yet, I'm not a big drinker, but to answer Chris' question, click on this link to solve your problem!
I purchased a bottle at the pier store in Progresso in October on a cruise and haven't even opened it yet. I plan to try it soon though. If it is a good as everyone says, I will be buying more in April when I go back. I think this might turn out to be the only good thing about Progresso.

I went on a Carnival "Fantasy" Cruise December 2007 and loved this soooo much that I purchased a bottle (by the way, if anyone knows how to get in touch with Marco from Serbia from the liquor gift shop let me know). This is a great drink and a fine way to relax. :-)
Sheridan's is also a family favorite. However, it is not sold here in the US. I had one liquor store by me have a distributor who was going to start selling it here, and gave them four cases, I bought one of the cases, and glad I did, as it did not perform as expected and they pulled it. Each time I cruise, we come back with no less than 6 bottles to get us through to the next cruise.
