Anyone notice a change in # of sales when you change your business policies? GD Hurt my sales!

I've tried opting in to guaranteed delivery twice. Both times, sales tanked as a result. Have you made changes to your business policies and noticed sales dropping off as a result? How long does it take the search to pick you back up after you change your policies, if that is the case? Thank you!

I have started doing calculated shipping on shoes and my sales sales have stopped.so sounds like a similar problem.

Yes, I have noticed this for years. Every time I bulk edit or make any changes to my listings, my sales tank. I have no idea when they get back to normal, if ever.

How can you opt OUT if they place you into their program???
