(Newbie) Payment providers charging 1.4 to 2.9%. That is a lot! Am I wrong?

Complete newbie here:

I am in the process of setting up my online course & webshop and I am looking into webshop platforms and payment options. I find that payment providers charge between 1.4 and 2.9% of the price of the items sold. In my case (enrollment to a year course is $2700) that is quite a chunk of the income generated (since these are small classes). Are there other ways? Or do I have to just suck it up and pay the price?

Thank you in advance for your kind suggestions.
