Excellent cigar provider
Given that a lot of the reviews here focus on pipes and pipe tobacco (which is only natural because that's their specialty), I thought I'd add that Pfeifen Shop is an absolutely excellent provider of cigars. Their selection is surprisingly wide and the prices are extremely reasonable. You can buy individual cigars or tins and boxes, as well as accessories such as cutters and ashtrays.
International shipping was at a great price and very quick, and even with that cost factored in it still turned out cheaper than buying domestically. I've received two separate orders now and both times the cigars arrived in excellent condition in high-quality, humidified packaging. Their customer service is also very good.
With the cigar lines they stock, I will be making Pfeifen my main cigar provider from now on. If they expand to include even more lines in the future, I can't see myself shopping elsewhere.
