What Days of the Week Are Best For Sales?

I've updated my spreadsheet that examines your seller Etsy Statement information!
Answers these questions, for your own shop, with NO MANUAL ENTRY of any information.
It uses the information already provided for you by Etsy. Just Copy and Paste.
(Assumes you have and know Excel.)

>What day of the week is better for MY SHOP for sales?

>Do Showcases work?
>Is renewing increasing my sales?
>Does listing new items help sales?
Examines the above questions in $ and # formats.

>How does the overall money I pay a month on Etsy relate to my number of transactions?

I'm asking for a few testers of this before I offer it in my shop. Just drop me an Etsy convo with your email address and I'll send it your way
Thanks for your help!
