Anyone ever purchased Cialis from one of those online (mostly Canadian, I believe) pharmacies? Did it work? Side effects? Can you recommend one?

Great question. I would be interested too but a little fear factor holds me back.

I get it from Lloyds pharmacy online they will either send it or you can pick it up at one of their stores.

I've got Cialis from an online pharmacy. It was no different than what you get at Walgreen's.
I use Planetdrugsdirect.com. They're legit, their service is great, and shipping is relatively quick. You do need a prescription.
In certain cases I also use them for regular prescriptions. They're cheaper than using insurance.
