For the average person.... Yes, I suspect you could buy two Blizzards at the regular price....  For the OP, I suspect if he could not get it on sale, then it was not an option....

When I go to the local grocery store, I check to see if bananas are on sale.  Regular price for bananas is something like $0.55-$0.59/ lb.  When they are on sale, price is something like $0.29/ lb.  Generally these are bananas ripe - getting close to being not saleable, so price is reduced to move them.   One day, I sat down and calculated the price difference.  I decided that I could afford to buy bananas at regular price if I really wanted bananas.  But my mindset is that I was looking for a bargain.  I suspect others have that same mindset - including the OP.   Reality is that bananas at regular price tend to be green, and not ripe.  If I buy bananas at regular price, I would have to bring them home and let them set around until they ripen.  So, I would really prefer the bargain price bananas as they are ripe.  But they also have a shorten shelf-life.  But that is beside the point.... I have a mindset to look for a bargain.  I suspect others do as well.
