What do you call this marketing strategy?one company is offering two products: one seemingly a bad deal and one seemingly a good deal.

I can't put it into words since English is not my first language but the concept example is this: An internet company is offering 6 mbps internet for 20$ and also offering 25 mbps for 25$, you will be inclined to avail the latter because its speed per dollar ratio is better than former. via /r/business https://ift.tt/2NQFnbl
