Sydney Padel Club review for NoBox: PO Box Blocker

We ship heavy items often PO boxes are refused. It was a nightmare having to email customers constantly to ask for a real address before fulfilling the order. Tried another app before but it was too complicated. This one just sits in the checkout and stops them from paying if they type 'PO box'. The dashboard is pretty basic, but honestly you only need to set it up once. Does the job perfectly.
