Shopko is giving $10 off $30 coupons with an email subscription sign-up and they are delivered quickly (within 10 minutes for my 3 emails).
They also have the Nerf.... Raptorstrike on sale right now for $29.99 and the coupon works in-store or online for store pickup however the store pickup has been having issues since last night and my online order is still processing so I went to the store and purchased instead. I'd avoid store pickup if you are worried about it going out of stock and missing it. My son has been watching YouTube videos of this Nerf Gun and is obsessed. It's also very big for a Nerf Gun.
You'll need a filler item greater than $0.01 to use the coupon. I used a $1 hot wheel in store for a stocking stuffer. Came out to $21.09 plus tax total.
