Etiquette dictates that guests should never show up empty-handed. While we wholeheartedly agree with this rule, it can be hard to come up with a clever housewarming gift, especially at the last minute. Of course, you want to snag a gift your host will genuinely appreciate—while still being able to make it to the housewarming party on time. Thank goodness the grocery store is a wellspring of useful, creative, and budget-friendly gifts.
