I've been very pleased to discover Eyecart.ca. I've only recently begun combatting a pretty serious case of dry eyes (it escalated quite quickly) and I found the eye drops available at Shoppers or London Drugs to be very pricey. Eyecart sells the same drops for cheaper, but also introduced me to some other brands, which I've had more success with than the ones previously bought in other stores. The delivery is also super quick, so I can place an order when I notice a bottle is running low and can expect the drops to arrive in just a day or two later. Super convenient and cheap as well!
