Just received some news from Sellfy:

Hi there,

We have important news about your Sellfy account and your store https://sellfy.com/mathtuition88

You have been on our transaction fee only plan (Legacy plan) since you signed up for Sellfy. We are truly thankful for being with us all this time!

Due to considerable technical adjustments in our platform and supporting services, we are forced to discontinue the Legacy plan on February 1st, 2020 and switch into supporting subscription-based plans only https://sellfy.com/pricing/. We no longer offer Legacy plan for new users since March, 2016.

Most likely, we won’t be continuing with Sellfy after February 1st, 2020.

Hence, this is the last 1-2 months to purchases math notes/material from our online store: https://sellfy.com/mathtuition88 if you are interested. Thank you for the support!
