Made my 10 best sellers FBM with good results so far

We have been FBA only for just over 3 years.

In view of the fact that free delivery for Prime customers is being quoted at a week, yesterday, at 6.30 pm we decided to put our best 10 sellers available for FBM. Since then we have had 16 sales from FBM and only 4 from FBA.

We are in a fortunate position in that our items are small and can be put in the post box in a mail lite envelope. My only fear is my for my account health.

Just thought I would put that out there.
