User blog comment:Dlewded/Woodwind vs. Apple Store/@comment-5110983-20120623225838

I'm currently powering through the hell levels 32-38 using florist stores. Yes they aren't great, but at least they give a steady rate of return of 5% per day, doing 8 medium recipes and 1 long recipe. This also gives 14,000 experience per day.

The Teradactyl Trainer and Woodwind stores give less exp per coin spent, and have rates of return around 1-2%. They just didn't make sense to me.
