Email sent with Incorrect link for discount renewal

I received an for mapSVG with a discount to renew and the link is changing full price. I am happy to renew with the discount priced and after spending 10 minutes finding this it would have been cheaper to pay full price.

MapSVG: the last WordPress map plugin you’ll ever need: Interactive Vector / Image / Google Maps
Price will increase to $38.50 from 29 Nov 2019 [Extend support for $27.50]



I have checked that link will take you to the plugin support page.
may be on 29 Nov 2019 your current support period will expire and if you extend support within current support period you will get it for $27.50 and after expired price will be $38.50
