The simple answer is that Amazon is a much larger company than the distributor, so they can buy the product at a lower price and still make a profit.
However, there are a few other factors at play here:
- The distributor may be selling an older version of the product, while Amazon is selling the newest version.
- The distributor may be selling the product in limited quantities, while Amazon has a much larger inventory.
- The distributor may be selling the product at full price, while Amazon is offering it at a discount.
In any case, it's generally safe to assume that Amazon is selling the product for less than the distributor because they're a bigger company with more negotiating power.
