I've run across this twice this week ... two different stores ... so I thought I'd post so others can keep an eye out.
1. Walgrees had SAMY Esencia Shampoo with a "try me free" tag around the neck of the bottle. I paid $7.99, but submitted the rebate for a full return. This stuff smells AMAZING!
2. Target has Organix Shampoo and Conditioner with a "try me free" tag around the neck of the bottle. I got the coconut milk conditioner, but they also had tags around the shea butter, teatree mint, and pomegranate green tea "flavors". I paid $6.99, but submitted the rebate for a full return.
These seem to be high end products, so hopefully you can find some too.
Good luck!
