It depends on your state. Some states like Florida, you can just apply for a position. Other states like Cali, you need to be PTCB certified prior to starting as a technician. Check the laws for your state.
If you are in a state where you can just walk in, do so. Its not difficult to get a job at walgreens or CVS, unless you are in a strictly college town where a lot of pharmacy hopefuls are. Even with that, I still got the job I wanted as a IV tech, and was offered a position at walgreens (of which I turned down).
My first pharmacy job was actually volunteer work. I did so for 3 months, after which I was hired on as a pharmacy tech II. I worked there for a little over 8 months before moving and getting this new IV tech position. If you want a job, most likely you can get it.
