Oftentimes, Checkpoints will ask you to scan several different items by the same manufacturer. For example, suppose you need to scan both NyQuil and DayQuil, but your store only has one. Or you need to scan both a bucket and bottle of Oxy Clean, but the store only sells the buckets. Turns out it doesn't matter.
As long as the products have the same parent manufacturer, you can scan the same product for multiple points opportunities. I had five different DayQuil/NyQuil opportunities but was able to collect on all just by scanning the same DayQuil five times.
Just an opportunity if you're having trouble finding what you need.
