Walmart offers two Halloween Airblown Inflatable Decorations in four characters for $20. (Monster Treater Airblown Inflatable is pictured.) Opt for Site-to-Store pickup to dodge the $4.97 shipping charge. That's $49 under the lowest total price we could find for two shipped inflatables elsewhere. Each measures approximately 36" to 42" tall.

Note: A Hello Kitty inflatable character is available for an extra $5.
