Single application of Frontline for Dogs

[LSAR]

I am looking for a single Frontline application for a 40 lb dog.  Low cost. Anyone have one?

There are several 3 month doses on ebay ranging from $15 to $25. This stuff does not expire; I checked with the manufacturer because I found some in a drawer from last year, so I called them.

Be careful buying it from eBay...you have no idea about the quality if the drug.  Have you tried asking a vet if they will sell a single vial?

I usually pick it up at menards when on sale for around $30/35 for 3 doses.
