I hate when companies compare their prices to food, beverages or entertainment ("cheaper than a cup of coffee!"). Unless your product is giving me the exact feelings and enjoyment that 18 bottles of beer would give, it's not a good comparison.
It feels like whoever is writing the copy is somehow belittling me. It's an overreaction, but I read it as, "you're a goddamn yuppie who would spend $4 on a cup of coffee. Why won't you buy your product, since your money seems to be burning a hole in your pocket?"
I hate to be negative, especially for something done in a lighthearted manner and probably as a parody of this trope in applications[1], but calling $649 a lot of pizza not only doesn't convince me, it makes me feel bad about myself—never a good idea to sell a product. Even cosmetics or fitness products are sold with a message of empowerment (you could look great!), not of belittlement (you look horrible, do something about it!).
