 ====== Purchasing supplies ======
+There are three common methods for making purchases:
+  *BennyBuy
+  *Department Credit Card (administered by Kelly Carter)
+  *Ethan's T&E Credit Card (administered by Ethan)
+BennyBuy offers a "punch through" to access selected company websites. Then you can purchase your shopping cart using a research index. I enjoy using the BennyBuy punch out to purchase stuff from McMaster Carr and DigiKey (good prices, good deliver time). Be warned, there are companies on BennyBuy that overcharge for basic supplies. For example, ThermoScientific may charge 3 times the normal price for a box of microscope slides.
+BennyBuy allows you to make purchase orders from a set of registered suppliers, including KAYAKU ADVANCED MATERIALS (photolithography chemicals). Remember to write the email address of the company in the BennyBuy comments box when you submit the order.
