Due to the complexities explained above, the printing industry has what are called overs (more finished product than ordered) and unders (less finished product than ordered). Industry standard says that it’s acceptable to have up to 10% more or less product than the quantity ordered, especially for customized products like ours. However, the Cool School Folder Company does not ship overs, only unders. This means that you will never be charged more than you’re expecting, but it also means you could receive up to 10% fewer folders than you ordered (personalized folders only; nonpersonalized items are subject to 5% unders).
