I used this website (but then the Dutch version of it) for my contraception pill (Yasmin) and asthma inhaler and loved how quick the service was - next day delivery and no need to go to my own doctor's practice! Got a confirmation email with a reference number for my parcel so could track it on the website of UPS - handy. Would recommend it to anyone with a busy lifestyle (or too lazy to get out of the house ;).
Lots of information available, questionnaire that helps move things along and prompts you, easy to use, efficient and speedy replies with an online service means you don't have to leave home. You don't have to book an appointment which may not be at a convenient time so you get what you need at a time to suit. Most important you have a trusted supplier for branded products.
