$25 a bottle? It costs at least $15-$16 and up to $20 in some places in TJ. Other places charge more.
I remember a source years ago that sold Brovel t 200 for $25 so I know it can happen. The person must buy alot of product and pay about $10-$11/each for them.
They work good. I'd buy alot if I were you. You usually wont see them for less than $40.
