Target Stores [View Ad] offer a $5 Target Gift Card for Free with the purchase of 2x 4-Packs of Red Bull. The Red Bull is $6 per 4-pk, so your total would be $12 for 8x Cans of Red Bull + Bonus $5 Target GC. [Store Locator]. Thanks Shakes30
Note: Exact price of Red Bull may vary by store, but many Slickdeals members have reported the above listed price at their local store.
