Did I buy the right thing?

Hi, I am new to this. I just received my complete parasite cleansing program which I ordered from the Dr.Clark store. It included Black-Walnut hull-tincture, Wormwood caps,clove caps,ornathine and arganine. I just came up on a site called drclarkstore.com that sells the cleansing kit for significantly lower prices and they say their Black-Walnut CAPS are surperior to the tincture. They also don't include the ornithine and arginine, are these 2 really necessary? Did I get ripped off? Thanks, Dawn
