I have a new theory.
Kevin Theory #32346.67-Z:
Amazon is in bed with UPS and receives kickbacks when they split an order into more than one shipment. I bought three books yesterday, all of them were listed as ‘in stock’. However upon checkout I was presented with the option to group my shipments to save money or ship items as they became available. It wasn’t clear which of the three was the holdup.
So I removed book A from my cart and tried again. B and C would both ship immediately. I added A and removed C – now A and B will ship immediately. I don’t need the books right away so I bought all three and had them shipped in one shipment. I got a shipping notification listing all three. Something isn’t quite right. Software oddity or conspiracy?
