With $39 free shipping, I noticed a thing a couple times. I had a cart worth $39.30.
I browsed for a while more, then came back 1hr later.
I was notified an item has dropped in price by 40c.
But now I need to add 10c of items to get free shipping.
Coincidence? It seems to have happened a couple times.
We know Amazon have in past varied pricing according to how much they think you would pay for an item. They were caugt and promised to not do so again.
This could be a different type of reactionary discount cuz hey see I'm still browsing and I would probably add an extra item.
