Seasonal Hiring Question.

Hi so sorry if this is a dumb repetitive question or has been asked before. So I applied back in the springtime at different locations for semi-annual sale. They for whatever reason didn't choose me cause I think they just didn't have many positions available which is understandable. I would like to apply again for seasonal which I know they will start soon probably in September. I was just curious if they're going to post new positions to apply for seasonal or if they will keep and use the old ones they had for semi-annual sale? If they do use the old ones I'd there like a way I can re-apply then cause I'm afraid then if I can't then like my old applications will be too far down for them to notice my application cause I am interested in working and helping them for seasonal. I know I can talk to the managers but I don't want to bother them cause I know they are busy!
