Let me say up front I don't have Amazon Prime so I don't get free two day shipping or what ever it is.
I ordered some Blu Rays off of Amazon yesterday and had the option of "Free Shipping" with an estimate delivery date of next Saturday or pay extra for expedited shipping. Two days, four days whatever the options were.
I'd chosen "Free Shipping"... and got my package in 24hrs!
Many times I've ordered 2/3 CDs to take advantage of their free shipping( over £20). The number of times the items have came seperately and by different couriers, is often.
You just never know, right?! I'm just thankful I didn't waste money on expedite shipping since I got my package in 24hrs anyway. That's a record BTW! I've gotten packages in two days with free shipping, but never one day.
