When I had a similar problem, I used CanadaPharmacy.com it was $46 for one vial of humalog, with $10 shipping. I think it was $10 for shipping no matter how much you are getting. I also did not need a script. If you have one, you may also try online US pharmacies, which may also be cheaper. It probably depends on the brand of insulin you use. Also, you could call around and ask places like Target and Walmart. I remember when I was looking for where had the cheapest pills for patients without insurance, Target actually had the cheapest, and sometimes it was even less than an insurance co-pay would have been. Good luck!
