Get a large Little Caesars classic pepperoni or cheese pizza for $3.99, only when you order online using the app or website for delivery. Limit 3 per person, per day. Plus tax where applicable. Only valid at participating Little Caesars locations. Delivery fee applies. Small order fee for delivery orders less than $10. Valid 4/20/20-4/26/20.
I don't see the offer posted on Little Caesars' website yet and the Facebook ad mentioned my specific region (Metro Detroit), so it's possible this offer may be region-specific, hence the YMMV.
