Based on the above I assume that goes for things like a DJI Phantom or Inspire? If someone had a desire to review a history of price drops, price undercutting, and new model releases I propose that company is a good place to start... Your comprehension of business appears woefully shallow, and your competitive statement carries no logic.
Business is about making money. A consumer business has silly things like cost to margin factors working all the time. Most successful manufacturing businesses have a pretty high selling price compared to the actual production cost, leaving them considerable room to move with pricing. While interest and demand is high so is the margin. If interest or demand drops the margin has room to move in order to increase interest. Then we have the inventory factor to contend with. Inventory for the Christmas holiday season is increased to assure dealers have stock on the shelves to meet customer demands. Will the season be solid or soft? You target what you hope it will be but if you over estimate you have to clear the excess inventory, especially in states that levy an inventory tax for product you have left on the self.
Using the links to review the lower pricing I see a couple of them are high volume businesses that operate on low margins. Adorama and Beach buy in very large quantities, have lower product costs because of those quantities, and can sell off excess inventory below cost if desired without harm to them to clear out inventory. Another appears to be a business that may well be simply trying to capture a few post Christmas dollars.
There are a lot of reasons to reduce prices, and I suspect some Amazon sellers have a lot more inventory on hand than they want now the peak selling season is past. You might view some of them as "clearance sales", which occur with just about every kind of consumer oriented business there is. Don't buy a new car at the beginning of the model year only to get angry when dealers cut thousands off the prices at the end of the year.
Lol.
