The best party favor is one kids actually use and parents don’t quietly toss. That means changing your goal from filling a bag with the most items to finding a few good things at a great price. Start with a theme, but don’t be rigid. A Bluey or soccer party doesn’t require licensed everything. A color scheme, a single activity, or a favorite snack can tie favors together. Once you pick a lane, set a hard per-kid budget: $3 to $5 is plenty for most parties. If you have 20 guests, that’s $60 to $100. Knowing that number keeps you from grabbing impulse items at checkout.
