I did not need 500 index cards an only wanted to buy a 100 pack but the shelves were not stocked and the only ones left that were in 100 packs were blank cards which I could not use I needed the lined ones. So I ended up having to buy the ridiculous amount of 500 index cards because no one restocked the shelf. The cards worked because how could they not but I was not happy about having to purchase the largest amount when I did not need to.
