What does it mean if you are incredulous?
1 : unwilling to admit or accept what is offered as true : not credulous : skeptical. 2 : expressing incredulity: an incredulous stare. 3 : incredible sense
Isn't it truly incredulous, ^^^
how their products are (according to their info)
both cheaper and of much higher quality,
than your other previous offers were?
And equally incredulous, is how they seem to expect that you will want to purchase them, if only they offer that same item or service to you, several more dozens of times!
