Some of you may already know this, but for those of you who don't. Today I went to my local Co-op, an all around feed, livestock supply, hardware, etc. store & got syringes dirt cheap. I bought 16ga needles for 25 cents, 3 ml syringes for 25 cents, & 6ml syringes for 55 cents. I tried them out when I got home & they work great for filling carts. Previously I had bought some syringes from my drugstore but the biggest they had was 28ga & it was too small to draw the eliquid. What's nice about these needles too is they are longer than normal needles cause they're made for cows & horses. You all have been so helpful to me I hope I can help you with this tip.
