I work in a pharmacy. We usually recommend the Jobst brand. They are gradient compression stockings, which means the maximum amount of compression is around the ankle and weakens higher up the leg. This has been shown to promote circulation better than uniform compression stockings, which have the same compression the whole way through and can therefore cut off circulation higher up the leg. Scholl Flight Socks are also gradient compression, but are a lower compression than the Jobst. However, they are also quite a bit cheaper too.
Something else to keep in mind is that pharmacies may not have stock of the Jobst products and may have to measure you and order them in - there's just such a wide range of sizes, compressions, styles (e.g. knee-high, thigh-high, waist-high, open toe, etc.) and colours that it's just impossible to have stock of them all. They should be able to get them in for you by the next weekday, however!

if we stayed at a much cheaper hotel, we stayed at PPH in 2009 but also got a great deal on that $110 per night.
which we're both dying for!
