Hi Mesnik!
The cost for Anna's berries course is correct. It is 150$. Duration of the whole course - more than 5 hours and it includes very detail information about creation berries. This is 6 years experience of work with berries. I think it is correct price for such experience.
About price for Elena's tutorials. If you click to Jellyfish tutorial you can see the price 58,8$. I think it is mistake of Etsy.
But the difference 4$ between my price and Elena's price can depends on currency course between Roubles and US Dollars. Thank you for your remark. I need to check it with Elena. It could be a mistake.
Merry Christmas!!
