Anyone used this online site for Minoxidil?

Hi all,
I have been on propecia for 8 months now and I am happy with the results overall so far. However, although my receding hairline appears to have stopped, I am still unhappy with the weakness of the hairs there. I am considering starting minoxidil also. I am thinking about buying the Kirkland brand off the onlyhairloss (.com) website. Has anyone used this site before, i.e are they reputable?
I would really appreciate any feedback,
Brendan
