Based on the elasticity of these products, what strategies besides pricing can be used to increase overall revenue for these three products?

Godiva -0.8

Hersey -1.4

Cadbury Eggs -0.7

Cadbury Dairy Milk Bar-3.9

Since Godiva and Cadbury's Eggs are inelastic, could one of the solutions be increasing or maximizing inventories at key stores and looking at end caps for positioning within the stores to help increase sales? Then what could be done for Hersey and Cadbury Dairy Milk bars that are elastic and not a necessity?
