I did this method awhile ago, like a year ago, and I still get trickles of money into my bank account but it ain't nothing. Maybe like $1-0.30 a month now. The time invested is not worth a buck or two a month. Even though I worked on these books during my 9 to 5 job, I still invested probably 40 hours into each book. I have about 5 published. I actually took the time to get good recipes, changed the wording manually to avoid duplicate detection, and paid to have covers made. The time invested is pennies to the dollar. Unless you like breaking your back for weeks just to earn like $0.30/month, by all means, go for it. Granted, it's still "passive" income, but I've definitely moved on to other methods that pay A LOT better. Good luck with anyone who actually tries this.
