My website is https://packaged-gases.com. There are several issues with ordering, payment and shipping: 1. As shown in the attached image (shipping.jpg), I charge $50 flat shipping per item. There are 4 items would should cost $200 for shipping but only $150 is charged. 2. In PayPal (paypal details.jpg), the order details only show 3 items @ $295 instead of 4 but the amount total is correct. 3. In PayPal (return to merchant.jpg) when you click on "Return to Merchant" you get an error. This is one of the most poorly written themes I've used.
