soil Nice gesture, can I substitute

My wife was offered a bag of "Garden Pro mini pine bark nuggets", bag says 5/8"-1 1/2" size. Now I know I can use this as a mulch, but as a crude substitute for pine fines. Searching around and can't find any local. I see this is sold at Lowes and they also sell a pine bark mulch. So much is written, pros and cons. Really don't have time to research, since I've started to return to work and am short on energy and patience. Thanks ahead.
