Note that on Injection Shop, you'll need to spend $50 to get free shipping. So you'll have to order 5 vials if you really want the $9.99 price. The discount code cannot be applied to the BAC water, and they will not allow you to order more than 5 at a time. So your total will come out to $49.95 and you still won't qualify for free shipping. So you'll probably add a box of syringes or some cheap alcohol pads to bring your total to over $50. The discount code will apply to these ancillary items. Kind of confusing, but you'll find that they process the order and ship quickly. I was very happy with my experience and will order again from them.
