JOB QUESTION: What should I do?! (please answer)?

I work two part-time jobs. One of them is at Giant Grocery Store making 6.60 and hour, and the other is as a Dietary Aide at a nursing home making 8.48 an hour. I've been working at Giant for about 2 months, and I just started the job at the nursing home a couple weeks ago. Giant is right down the street from me so it only takes me 5 minutes to get there, and the nursing home is about 20-25 minutes away. I get a lot more hours at Giant which is what I need and they would give me more if I wasn't working at the nursing home, which i'm only getting like 2 days a week. I've been thinking about quitting at the nursing home and going full-time at giant as a different position making a little bit more probably 7 something or maybe 8, so my question is, is it a good idea to quit the job that pays more for a place thats closer and I get more hours?Or should I just stick with both? What would you do? Stick with both, or just work at Giant? And I dont want to quit Giant bc of its flexibility...
