You’ll find the prices for ABS compounds and regranulates online. I only happen to know sources in German. But the prices are the same: ABS is around 1.80 Euro per 1000 gramms. Recycling around 2 /3 of that.
So saving some Matrial will most probably not be worth it. At least if you are looking at more than 2 Euro retail for your product.
