Non-numeric value encountered in Shop

Hi Drew

I'm getting the same warning message as this thread when I switch PHP up to 7.16.

It occurs when a product is added to the cart. It continues when delivery options and static cart is called further down the line too.

7.0.20 doesn't throw a warning, so I've gone back to that.

There are no non-numerics in my prices, taxes etc.

Kind regards
