 They claim that the prizes for which they had been saving are either constantly out of stock or are no longer available.Some items experienced steep unexpected price increases, as well; for example the coupons for a free 20 ounce bottle of Coke increased 67% (from 24 points to 40), a $75 Blockbuster gift card which used to cost 722 points went up to 1,020 points (a 41% increase) before being discontinued, a single Napster download went from 35 to 70 points from 2010 to 2011 (and 10 from 350 to 700, a 100% increase), and the price of a GPX docking station went up from 975 points to 1,820 (an 87% increase).These increases took place at the same time as Coca-Cola was taking drastic measures to decrease the number of points awarded (through its February 2009 rule changes which reduced the maximum number of points from 1,750 per week to 75 through 22 March 2017).
