I've been going to them for a year and was buying their dirt cheap dutasteride (it's not avodart btw, it's dutas by dr. reddy). Not sure if you know this already, but the shipping is expensive so that explains the low price. It's worth it if you buy a lot from them.
I was only able to pay by check b/c they only accepted checks from Canadian customers. Shipping was pretty fast and they ship it out before they receive the payments so that's good.
Whether the drugs are truly legit or not, that's what I can't tell you. The packaging looks legit from what I can tell, but I had terrible results from using dutas. It was my first time using dutasteride, so I'm not sure if it's their drugs or that I just don't respond to dutasteride. Check google though, other people use alldaychemist and claim their drugs work.
