Hey! Thanks for reaching out! Are you using a Square Online Store or are you using an older Weebly website? With Square online you can have unlimited items, but with older Weebly websites you will need to upgrade to a plan higher than Pro in order to add more items.

It says upgrade before anybody else can buy
