Unfortunately, no one has been able to give you an answer on how to avoid paying fees because there is no way to do that anywhere to the best of my understanding anyone suggesting a particular site, you just need to watch it. The way out is to avoid doing small payment and wait till when you can afford it before you try sending. Also, you can download the bitcoin core and try from there but be sure to pay some fees as you can only reduce it but not avoid it altogether.
