Due to my prescription plan, I am unable to purchase from most pharmacies (I work at a refail company with pharmacies in-store “I owe my health to the company store”).
The drug I currently take for seizures is currently unavailable in generic form here, I think. 60 pills of Vimpat 150 mg costs about $800 (holy crap until I reach my yearly deductible, then $20 after that).
I checked a Canadian online pharmacy, and I can get 800 pills of lacosamide (generic form) for less than $500. THIRTEEN TIMES more, for two-thirds the price. OVER A YEARS SUPPLY.
