I checked Debra's website out- but was dissapointed that there were no prices listed or shopping cart to purchase online. You have to dial the toll free number first and answer some questions.
I always get nervous with companies like that-- where a customer service rep wants to talk first and get you to buy more things than you really intended-- before handing over the controls.
If I wanted to buy the parasite drops- I guess I'd have to call the toll free number first and wait for them to give their sales talk before I'd find out how much the price was.
Neverthless, I'm glad that the products worked for you!
