Target carries lots of varieties of the 5-packs of Hot Wheels Cars and Marissa noticed a price cut on all of them for $4.49 thru 7/28. Price Cuts can vary  by region, but if you find the same it makes for a nice deal…

Hot Wheels 5-Packs $4.49 (PC thru 7/28)
$1.00 off HOT WHEELS 5-Pack
= $3.49 after coupon and price cut (regulary $4.99)

Thanks for the heads up & picture to Marissa!
