Ok, https://shopinbit.com/forms/index/sFid/27 looks very shady. I double-checked if you're the Max I'm following but their stories about discounts going back to mistakes on part of the vendors doesn't feel right.

I just know that the service makes arranging travels a breeze (I guess your OP was about a lack of convenience), and that the discounts and upgrades work sometimes as well (not all the time, it depends on flight or hotel).
As I trust you, I consider checking them out but they look so shady ;)
