Hello everyone. I found a reputable online pharmacy (UK based) selling Provigil (also known as Modafinil or Modalert). It's 3 or 4 times cheaper than all the other sites. I have done exhaustive research on this since losing my insurance with my job last year. I bought it from here as well as some other family members who also have narcolepsy. Delivery is within 5-7 days.
Here is the link:

Hope this is of some help!
I also found this address Gomedstore.com which offeres generic Provil/ Modalert/ Nuvigil at cheapest price ever; 20% discount on the next order, fast and worldwide shipping!! I personally tried it and hope you can find what you need here!!
