How to go with Weebly pricing with Square account

I have Square account for my in store sales, been using it for a couple of years. Now I want to make a website, but I like Weebly pricing. Once I created Weebly account, it suggested me to connect my Square account for my inventory. Now wneh I wan to build a website, it shows me Square pricing ($36/mo) when I want to go with Weebly pricing ($15/mo). How I can do that?
