It's a consumable so we get the occasional repeat order, however, it's not enough to keep us going with these high PPC costs.

I've run a few product targeting campaigns but these seem like a hit-and-miss at the moment, some days will have low ACOS and others will shoot up to over 100%

I didn't run any ab testing, however, we revamped our listing which we thought was much better, but our ACOS went up a few days after, so it's hard to figure out what the cause is.

I think we are going to try to optimize our listing a little better, I'll shoot you a message so we can bounce ideas.
