You asked for feedback, so here's what I've got.
1) The page needs to be limited at the right end, instead of trailing off into the distance. Most people do not want to scroll sideways at all.
2) The different cigars should be separated better. Again, too much sideways room is used (wasted) so that the eye does not follow from the name of the vitolas and the prices, and vendors. And box or 5-pack is jumbled together.
3) Too much fealty to the single line per entry concept, which makes the thing hard to read.
All that being said, the really important thing is the database. If you spider enough to have fresh data, and not so frequently that the vendors make life difficult for your spiders, that info is in demand. The presentation, which still needs a lot of work, can AND WILL ALWAYS be improving, but the data is what will sustain you. If it is fresh info, and accurate, I think you have something good here. The only other thing like this I know of, from the cigar cyclopedia people, takes too long to load and is so old technology, so web 1.0. Get your Ajax humming here, and you could definitely have a winner. IMHO, natch.
