Go to the laundry aisle at Target and look for the packages of detergent packs pictured above. Find ones with a pink sticker that say "Try one free".
The rebate is good for a free product up to $9.99! The ones we found were 24 ct. for only $4.99. We looked for bigger packs but could not find them.
Anyway, keep your eyes out for this Try Me Free rebate next time you're out shopping!
