But there is no additional information in the general case. The amount charged for shipping is completely arbitrary. All you’re being told is that the price P is actually the sum of A + B, where A and B are just some amounts.
There are exceptions to this. For example, I trust McMaster-Carr to charge me whatever they get charged for shipping, which is good because they won’t tell you in advance what it will cost. But in general it’s just another number. It’s a really common scam to have a cheap item with expensive shipping in order to trick people who aren’t paying close enough attention.
Put it this way: store A is selling widget X for $40 with “free shipping,” store B sells it for $35 plus $5 shipping, and store C is $15 plus $25 shipping. Who do you buy from?
- mcv 8y agoBy that argument everything is "just a number". It's still part of the sum. For example, if C sells something else that I want that's also much cheaper than a the other shops, and it won't increase shipping costs much, then that's the better option. If not, I may continue to shop around until I find a shop that combines low item price with reasonable shipping cost.
- mikeash 8y agoThe sum is all that matters. The rest is just a weird number game. As you say, your store preference depends on various factors. If C’s shipping costs are structured one way, you’ll prefer them. Another way, you won’t. You have to know all those details before you can choose. That’s my point: ultimately, functionally, there is no difference between a random store that won’t show you prices until you give them your location, and a ransom store that shows prices immediately but won’t give you shipping costs until you give them your location.
