I did some research on this over a year ago and at the time thought DistroKid was the best possibility. However, I'm just not interested in trying out any distributor for 2 reasons. The first is that I started self-publishing books in 2013, initially very hopeful, but over time I found that there was just so many millions of people worldwide producing eBooks on a regular basis that anything published just becomes another minuscule needle in a stack of minuscule needles. I haven't checked figures for a few years now, but last time I did Amazon alone had 49 million eBooks alone on sale - and the only books they'll promote are already bestsellers. Music is even worse as many thousands of new music tracks get posted daily. My 2nd reason is that I'm a UK pensioner living on State Pension and thus I have to declare any extra income, so even making a little money can cause oodles of bureaucratic problems as the system is designed to stop any kind of benefits payments, even when there's no good reason to. I sell on average about 1.5 books a year and as I posted free copies to friends worldwide after I first published paperbacks I've made less in royalties than I've paid out, thus my self-publishing is classed as a hobby from which no profit is expected to be made. You, Beth, are one of the few persons I know who may understand this, but how successful in any field with any kind of enterprise, dosh-related or not, you are doesn't depend on how much work you put in, or on how positive or enthusiastic you are (as 'new agers' like to think) it all depends on one's prarabdha karma. As great sages of many spiritual traditions affirm - and it's absolutely true in my experience over more than 5 decades - if it's in your 'script' it'll happen; if it isn't it won't.
