What method do you use to get domains for less?

Hi guys, I'm new here.
I have a future project and would like to know if there is any method and if there are any which you use to renew a domain on godaddy.

I've tried honey extension and searched for coupon manually on google.
If you use another method to buy domains your opinion is also valid.

Thanks for help me.

Use a different registrar which gives a much lower price. For example, Namesilo

Domcomp dot com

I usually use coupons when buy new domains or renew them. Other way I'm using is transferring to another registrar with lower cost (or using transfer coupon too)
