They are selling so many of them they don't need to advertise everyone wants one.
Judging from last year 5.5 to 4.7 inch sales. The regular iPhone 6 outsold the iPhone 6 Plus by around a 3:1 margin. So every 3 phones sold is the 4.7 inch iPhone compared to one 5.5 inch iPhone.

Apple simply doesn't produce enough 5.5 inch models especially at the beginning of the cycle to meet demand. But once demand catches up to supply Apple still sells more 4.7 inch iPhones. Biggest factor is the price. The 4.7 inch iPhone is just cheaper

True, half the people I know would have gotten the bigger screen if it wasn't for the fact that they had to choose between a 64GB 6/6S or a paltry 16GB 6/6S Plus.
 
No doubt price makes the difference. I work for a major wireless carrier and the demand for the 6S Plus was insane at launch. Many people "settled" for a 6S when they wanted the plus, but couldn't get one. I'd estimate that if price wasn't a concern, about 70 percent of my customers would choose the Plus.
