The other thing with retail is that unless you're in management there's a good chance your hours and thus your pay not going to be consistent. You'll be able to get plenty of hours around Christmas time but the rest of the time your hours might fluctuate a lot depending on how busy the store is that time of year.
When I worked at Target a lot of people there worked a second job because they basically had to, especially if they had kids to support.
