I wasn't planning on this, but I have three books lined up for advertising on March 3rd, 4th and 5th. I asked in another post if I had enough time to schedule other advertisers for the March 3rd date, but I'm also wondering if there are any downsides to advertising the books so close together. This is my first time advertising so that's probably a downside right there, and I know ENT (where the books are set to be advertised) has a 90 day wait period until they can be advertised again. Should I try to space the books out? What are the advantages and disadvantages of having them so close together?
