Hi,
I've placed an order on your website and ordered the product "WASTE NOT Refuse Sacks". On the address selection screen, I was only able to select a billing address and not a shipping address. That means that the system didn't detect any shippable goods in my cart. The system decides whether a good is shippable or not by looking at its weight. If you don't set a weight, the system consider the good as virtual (like software downloads for instance) and won't propose any shipping methods.
Please make sure you set a weight in your products information.
