Quantity tiers
Instead of one price, a title has a price for each quantity range. For example, one price for 5–9 copies, a lower price for 10–24 copies and a lower one again for 25 or more. Every title has its own tiers.
How tiers work at Global Academic Supply
Most titles start at 5 copies, and many step down at 10 and 25 copies. Titles with a 100+ tier are quoted individually. The exact tiers are listed on each title page. For example, open the page for
Research Design, 6th Edition to see how a tier table looks.
Compare the price per copy at your quantity
The single-copy price tells you very little. Look at the price per copy at the quantity you actually need, then multiply by the number of copies for your total.
Check the quantity boundaries
Sometimes ordering a few extra copies to reach the next tier lowers the total cost, and the extra copies can serve as spares or reserve copies. Compare the total at your quantity with the total at the next tier before you decide.
Compare everything that affects the total
Look at shipping, tax status, condition, whether the ISBN and edition you ordered are the ones that arrive, and delivery time. At Global Academic Supply shipping is free on every order, and books arrive brand new, shrink-wrapped and well protected.
