There's a couple of coupons on redplum.com that you need to print. Save them and wait for a $1 sale at your local grocery store. If your store doubles then you are looking at getting them for free. I'll be checking my local Giant PA and will update if they are on sale.
50c/1 Grill Mates Blend, marinade or spice rub. This was also found in the 4/18 red plum insert in the paper too.
50c/1 Lawry's Marinade
