I sometimes see items on you prime choice picks that are not easy to find or do not exist. Case in point, anything made by Rexall. I finally found that Rexall is through the same company that owns Dollar Store. But I could not purchase your 1st choice. Can you include a link to purchase items like LabDoor does?
Please test more choices of each product. Looking at Amazon can help you narrow your choices if you look at the number of purchases of particular items.
