The pricing system was more archaic and manually driven than I expected. Vendor Managers were asked to review pending major price drops and raises. Later, a team in India/Pakistan would be the first line of defense, then the VM would be asked to review in edge cases.
We could easily manually lower the price, however raising it was very difficult and required managerial approval.
One thing I felt was anti-competitive was price matching Costco at the "each." This would result in absurd 2-day shipping prices that could not possibly be profitable. e.g Costco sells a 24 pack of soap for $1 per soap bar. We would price match the individual soap bar such that it was a $1 delivered to the customer's door.
France caught on to this "pro" customer behaviour and is implementing laws requiring minimum shipping charges so that E-commerce platforms can't use "free" shipping in a predatory pricing manner.
