Mugs I'm giving will include a hot chocolate packet and chocolate dipped peppermint stick or a black tea packet and honey stick (will vary by person). Either one is costing me about 75¢ each. I bought the mugs for about $1.25 each so $2 for total gift.
Do you have a local place that has a zipline or obstacle course? Maybe a gift certificate for that which would get him away from the video games for a couple of hours.
