Udemy just started one of the large sales of the year. Prices for courses are at a minimum right now; it doesn’t get any better. If you buy one of our courses, please use the referral links below. At other times, outside of low-price sale campaigns, you can always use our monthly code for prices that are almost as good as these sale prices. Our monthly codes are easy to construct: “TPOT_AUG23”, “TPOT_SEP23” and so on.
