£180 is a bit steep, but may include membership? It may be that the branch isn't making much off that. We have a max of 8 couples per course. We had hall rental at £140 per course, which was cheap, really. And then the teachers cost a minimum of £25 per hour. And then, you have to pay a % of your takings to head office. It all adds up.
Our branch charges £140 for a two-day, 12-hour intensive with separate 2-hour breastfeeding course, no membership involved. We make quite a bit of money on it, tbh, but it subsidizes all our other branch activities (e.g. newsletter). We don't pay any hall rental atm, otherwise we probably wouldn't make anything.
And yes, if you say you have financial issues, we can (and do!) charge less.
We also do a one-day, 8-hour intensive at £100. Nobody wants it, though, they all want the two-day.
We probably should lower how much we charge for classes, but demand is so so so high (I had a place come free recently, and had such demand for it, I did a draw between 8 couples!), and we can hopefully start training a new teacher or two soon with the money, so I can stop saying "we have no places for you" to everyone who gets in touch.
