確かにお金はかかるけど、それより行きも帰りも大きい荷物持って歩かなくて済むから・・・


> 確かにお金はかかるけど、それより行きも帰りも大きい荷物持って歩かなくて済むから・・・

Can someone explain what the the 済む means at the end of this sentence? My
thoughts are it means something is finished.

"Sure it costs money but on the other hand, I have to go and come carrying
this big bag, if I don't have to walk then I am finished?"
