Amazon has a Frozen Lunchbox Tin marked down to $6.80 from $9.99.
Plan Ahead: Pick a couple up for holiday gifts. Keep your eyes open for discounted dollar items at Target or school supply clearance and make a tin full of goodies. This could be something to consider if your school does a class gift exchange for around $10.
Keep in mind that prices flip fast on Amazon so be sure to verify the current price before purchasing!
