I can confirm that there are no charges for Selling Manager "regular", I use it on my non-store accounts.   For the most part, I don't really see much advantage in SM Pro - I don't really remember anything that I use on SMP that is missing on the freebie one.

Thanks, both of you. I did read about the fee compensation and good to hear that they're true to their word. Having a Selling Manager looks really good. There are actually a number of useful features. If you're making a good turnover, the Pro isn't very much per month but obviously for newbies who aren't selling very much it just makes sense to try the free one.
