If you get offered a job as an inventory clerk and you are the only person doing it, or are on a small team, make sure that you like working alone.
While some stores do this as a staff project, others segregate shipping and receiving duties into a back warehouse. This can mean many hours spent in solitude organizing inventory.
I think this job is great for people who enjoy keeping everything orderly and don't want to spend as much time with the public.
Usually this job starts at minimum wage. But it really depends on what your in charge of. The wage cap seems to be around $25USD an hour for specialized goods that require extra knowledge.
