You are welcome. I have ordered several things from the US (crystal light, Mrs Dash) and I often end up paying more in shipping than the actual product I have ordered so it is a bonus that there is no shipping charge for your acijel!! Yep ... last time I checked it was NZ $52.
It is a 100g tube which is about the size of a large tube of toothpaste and it lasts for many attempts. I use a fingertip full each morning from the end of AF to O and this month, depending on my pH prior to my attempt I am dropping the lime douche and just using acijel if I need to lower pH.
I found it didn't raise my pH and I think it kept it lower for longer than the replens but wanted to warn you that I know some girls have their pH raised with the vinegar douche, some with the replens and some with the acijel ... so everyone is different and you just need to try it before your attempt to make sure.
GOOD LUCK with your attempt.
