I thought I'd give using a syringe a try when my order gets here (VA). I just walked up to the pharmacy at cvs and asked for a syringe. they asked what for and i said to refill this (pointing at my carto). then they asked what kind, i said 25gauge (didnt know what that meant but somewhere on the forums said to ask for it like you know what you're talking about). Pharmacist went into the back, got me one and let me have it for free. It was disturbingly easy lol
