If your demand is free shipping or nothing, then yes, you get to know that fairly early. But I wasn't expecting free shipping on the item I ordered. What stopped me was finding out how much the shipping would be, and I didn't find that out until later on, and I didn't find out how much the shipping would be with Amazon, either.

True that it's given with Amazon Marketplace, and I'd forgotten about that, but this is items sold by Amazon itself.
