The teen boy is IMHO the very hardest to shop for when on a budget. The routine electronics and video games often cost a pretty penny. Your pennies aren’t pretty either? I’ve got your back.
Look for items the dude would use but wouldn’t necessarily buy himself: a sleek, wear-resistant watch; ties for prom, graduation or college interviews (‘zipper’ for the formal wear newbie) or a fun Wayne-chic sterling money clip.
