And what's even more interesting - human would do exactly the same thing.
Add items to card, check the total price and then decide whether to buy it(i remember trying to order some stuff form one japanese plamo store - and it didn't provide exact prices before checkout. I went through the process, but even the cheapest option for delivery was way too high - as 2x price of the whole order)
I've had that sort of experience with a Japanese store once--the prices were good but the shipping (the only thing they offered was international FedEx) killed it. The US is just as bad--we don't have slow international options.
