I do not understand what you are referring to.
The first project you linked, has a minimum price of 0 and an individual file price of 3.00 and a suggested price of 5.00. The second project has a minimum price of 4.99 and a suggested price of 5.00.
So, none of the projets has or had a minimum price of 5.00 to get the whole pack. But both have a suggestion of 5.00. Being on special offer does not change the suggestion.
