Anybody that uses Udemy realizes they have a very volatile pricing strategy. They seem to have prices that fluctuate between $10 and $20 due to many variables.
I am unable to purchase is a course for $12. Whenever I try to purchase the course it raises the price to $20. I have not bought any courses since July, so I should be elgible for coupon code. @mroberts is able to get it for $11.39
Has anyone figured out their weird pricing model and any rhyme or reason behind it?
