I'm using magento version 1.6. I am having this problem when using the guest checkout, it keeps displaying "Sorry, no quotes available for this order at this time" when i'm in step 4, which is the shipping method. I entered the right address, right zipcode and also the right country. But, if ill login with my account, i can see the right computation of the shipping fee.

I have googled around and I have read that I have to set in admin "Show Method if Not Applicable" to yes. I followed it but it doesn't help for me still.

And also, the issue only occurs on a certain product category, it doesn't occur for all items. For example: I have category 1, category 2, category 3, category 4. All products that belongs to category 2 and 4, shipping method will display "Sorry, no quotes available for this order at this time". But category 1 and 3, computes the correct fee.

Any idea on this?

Additional Information:

```
 Shipping Method Use

     1. Flatrate - Fixed per item ($3.00)
     2. Tablerate (Bestway) - Weight vs. Destination (I have no idea about the configuration of this). That is just what i saw in admin. I'm nob on this!
     3. Free Shipping - For every $500 purchase

```

Upon further investigation this is what i found out:  

 If the total cost in cart is less than $500.00, it will ignore the flat rate shipping method which is suppose to be the method to be used when its total don't reach 500. And, will return the message "Sorry, no quotes are available for this order at this time". But if the total in you're cart is greater than or equal to $500, you will see the free shipping method on the list. There is no other method showing up.

The problem here, the code below is not returning any value even if you set minimum value in admin. 

```
 $this->getConfigData('free_shipping_subtotal')

```

But if its cart total is >= $500, it all works fine.
