Glow in the dark paint

I have found some glow in the dark paint for fabrics at Gordon Harris, it cost 69.99 I think the student discount is 15% which will take about $10 off of the price meaning it will cost us all about $12 each to split. I would like to hear what everyone thinks of this price or is it too expensive? For outfits there will be further cost for the clothes themselves too but I don't think too much more. We can check spot light and made on Marion for more choice for glow I the dark paint but I am unsure whether they sell them. Please let me know what you all think and whether you can quickly check any places that would likely sell glow in the dark paint that is suitable for fabrics by tomorrow thanks
