I don't remember what my raise was but after that and the yearly review I'm making 11.30 an hour. I'm the only receiver but there's an indeterminate number of people who are allegedly trained and could work in the area but I have yet to see any solid evidence.
And a word of advice to anybody interested in becoming a receiver: do your research. Don't do what I did and only think about a pay raise and maybe weekends off. Try and find out why they're leaving, what condition it's in back there, if anybody in the store has a plan for training, how your leadership treats and supports receiving, etc.
