Vaginal applicators for Metronidazole

So I seem to have BV and still have a lot of Metronidazole left over from a previous time, but i’m out of the applicators. I’ve looked on Rite Aid, CVS, Walmart, etc. and haven’t been able to find any, so my question is do you guys know where they could possibly be found at? I’m trying to avoid buying them off of Amazon but i will if that’s the only option available.
