Placing a cheap item next to an expensive item to make it look more affordable.
"premium suits are often bundled in sets on reappearance to encourage players to spend more, particularly if you can only buy a suit you want with a suit you want less"
"The game does put cheap items next to expensive items, there is also first-time-purchase bonuses, there is a bundle"
"Offers bundles that are less cost effective as others and tries to make them seem more ideal"
"The game uses their gem currency to make things seem a lot less expensive than they are. For example: most dragons cost about 1500 gems, and they never put the cost of gems next to the dragon’s cost. So people end up spending 50.00 US dollars, because of the difference between gems and US dollars. 1500 gems = 50.00 US dollars"
"The cheapest box is 15K coins which requires a lot of game time. It makes the only twice as much 30K gold box or 300gem bigger boxes seem reasonable."
"The more scarcely billed VIP passes seem cheaper than the more frequently billed ones."
