It's not so much the learning and sourcing thats got me hung up as it is the sales tax issue. I'm in the process of getting my resale certificate for multiple states so that I can comply with the whacky tax laws that are involved. Once I get the paperwork end smoothed out and get over the learning curve, I will go back to my first love, writing.
My blogs and articles are what drive the Amazon Associates sales up, so I need make sure I give them the attention they deserve. My blogs are my first love over FBA anyway. I realize there is probably way more money in FBA (at the moment) but in the long run, I like income that pays out over and over again.
