King Soopers: $4 Credit When You Load 4 eCoupons?

Janet emailed yesterday with this:

I just loaded a couple coupons from the King Soopers site, and I got a message stating that if I send their “e-mail” to 4 of my friends about the P&G Buy 4 Event, I would get an instant $4 off my next order. Has anyone heard about this or tried it?

I filled out the blanks with four friends, but I don’t see a $4 coupon under my coupons. We will see if it automatically comes off at the register!

Has anyone tried this and had it work?  Does the $4 credit just come off at checkout on any purchase, or do you have to redeem the eCoupons that you loaded?

Here are this week’s King Soopers’ deals, with Tide for $2.99 and Old Spice Deodorant for $0.49!
