They're like $6 each if you buy them from this pharmacy in India. $600 Advair inhalers are $30-ish. The website I linked doesn't even ask for a prescription.
I buy them by the dozens. I never run out anymore. (It's good to over order, as it takes 6-8 weeks for delivery to the US.)
Separately, note that there is supposedly a temporary worldwide albuterol inhaler production shortage, so maybe don't over order this quarter.
Note that almost none of the drugs offered at these shops are FDA-approved. The Indian ones are mostly produced in accordance with the regulations of the local Indian counterpart to the FDA (generically, the NRA of the country is CDSCO). Some of the Indian drugs are counterfeits though, not produced in accordance with CDSCO rules but falsely labeled as such.
The Chinese chemical distributors are even less stringent -- for those you absolutely should provide your own QA/QC by getting an HPLC/etc test done by an independent lab ($100 or so per compound tested).
