I think that it depends on your will power. Will you be tempted to use the credit without the intent of immediately paying it off right after you swipe? If this has been or could be tempting, shut them down! The interest you will pay is way more than any savings you initially got from swiping. For me personally, I have never left a balance on a department store credit card past a billing cycle. I take advantage of the “perks or discounts” and then immediately pay it off. I personally have 5 or so department store cards, none of them have a balance. As far as closing them, this will temporarily impact your credit. If you intended on taking out credit for a car or home purchase, you might wait to close the cards until after your major purchase. CONGRATULATIONS! And keep up the hard work!
