This is easier then u think... goto the closet pharmacy, ask the pharmacist for what you want, pay, enjoy!
Maybe its differant where I am (canada) but that's all I do and they are only .30 cents a piece (includes syringe and needle). So yea I can get an entire cycle worth for like $12. And no they have never asked what they are used for or given me any problems.

Is it differant where u are? Cause I wouldn't see the point ordering online and waiting when it takes only 10 mins to get anytime.
