Or outright scams.A few of the links on non Amazon pages had prices but when I clicked the price was higher. Maybe surge pricing?
Ive seen several videos where people ordered things "on sale" as prime day offers, only to look back at what they bought and now they are significantly cheaper now than they paid "on sale". One example the guy showed where he paid $30 prime day price, the day after its now $20 plus a $2 coupon.
