We use Magento 1.4.2, PayPal Express.
I had a couple times where I had not got a quote or anything for shipping in shopping cart then I clicked to checkout with PayPal (I think was shortcut button in cart), and it showed no shipping.
On PayPal after logging in:
Once it said something about 0 method selected and showed 0 for shipping.
Other times it doesn’t say any shipping. If I log in I can’t afford to buy it and don’t know if I click “Agree and Continue” if there is some other step that would give the shipping options I get from my unishipper plugin in the cart?
