V. the combination of shaming and up selling. Up shaming happens when you are pressured by a retailer to make a purchase greater than you need, want or perhaps can afford because it is offered at a perceived discounted rate only slightly higher than the size you initially planned to purchase.
I got up shamed at the local drugstore when the soda jerk convinced me to buy the bigger sized drink for only ten cents more.
