I wanted a copter for a long time, and now the cashback forced me to fulfill my desire. Having accumulated 50,000 bonuses, I began to wait until the price was around 100,000. It took me 5 months of daily monitoring.
Pros
It is possible to pay 50% with bonuses, though it was hard to keep 50,000 bonuses for six months, so that they would not burn out
Cons
Came in an open box. I had to make 3 orders in parallel, so that at least one would come in a film.
