Cosmetic fix of furniture scratches

[DIYHaveaCrack]

I'm wanting to sell my bedroom suite (a bed base and headboard, 2 side tables and a chest of drawers) and it is in good condition however there are some scratches and marks (particularly on the chest of drawers) which I would like to fix before I put them to market. It really isn't worth my effort to sand back and re-stain whole items (it's more of a time thing) so I wondered if there was some kind of 'cosmetic' fix I could apply. I don't mind some elbow grease so if I had to sand a restain sections that would be fine (buty then I guess it would be a matter of matching the existing stain. Thoughts?
