Just one rebate but 2 products right? I just filled out 2 separate rebates because I bought 2 jugs at 2 different stores. HF only had one jug left when I went in early december so I bought a second jug right before christmas when ace had it down to $8. However, I saw that in a single rebate, you can add a product, which I figure is what you did. The 4 types of products were confusing too. It seemed like they had two 50/50 options and two concentrate options. I didn't know which 50/50 option to pick and just guessed.
