I used to get them at pharmacies no proble. I would go in dressed in a proper manner (I'm not going to waste time explaining this one, I think it's obvious) and ask for specifically what I wanted which I had written on a piece of paper. When asked what they were for I would respond by saying my dad sent me to get them to worm his dogs. They always forget about their suspicions and began asking about the dogs and sharing what kind of dogs they had. My dad did have a pen of hunting dogs, but they didn't know that. I just told them when they asked what kind: "6 Liver Pointers."
Not only did they sell me the needles but they were always very happy to do it.
Although, after trying GETPINZ.COM I prefer them. EXCELLENT service and EXCELLENT quality AND excellent SELECTION. The Terumo that getpinz uses slides into the muscle like warm butter whereas the others (BD) were definately duller.
