With orders of $25 or more, Amazon offers Prime members the Skittles Original Candy 9-oz. Bag for $1.85 with free shipping. (Non-members can qualify for free shipping with orders of $35 or more.) That's about $1 under what you'd pay locally in-store for a similar quantity, although we saw it in March for about 50 cents less.
Note that this item is part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more.
