Shifting Products from side by side to next row

In the product form I have the products side by side but I need the third and fourth items to shift to the next row so its not extended beyond the form border and is more uniform in design. 

Can you please check my version http://www.jotformpro.com/form/50366686862972

I cloned your form and modify the CSS code.

You can check what I did by cloning back the form also.

user guide: -How-to-Clone-an-Existing-Form-from-a-URL

To have 2 column payment, I followed the user guide

Let us know if this version matches your requirement or not...

Thanks.

Jonathan,

That works great, thank you....
