This is the best selection of low-priced costumes we could find right now.
Brad's Deals Editor Marisa,
Get dozens of kids' Halloween costumes for under $20 at Walmart.com. Check out this little girls' Frozen 2 Elsa Costume for $15, which is the best price we found on a similar one by $5. Shipping is free at $35, so you can shop their whole Halloween section to get to the free shipping threshold. Otherwise, it adds $5.99. Many items can also be ordered online with free in-store pickup. Sales tax is charged in most states.
