The nose knows! I am super sensitive to smells. When my house smells pretty I feel like I am helping my family put their best foot forward. In the past, I searched for the cheapest air fresheners I could find in the name of thrift. But, I really was not saving any money. I had to buy 3x the amount of product to enjoy a fraction of the quality of a Scentsy wax bar. When you add in a husband who is prone to allergic reactions and an African grey parrot I need to keep safe, buying from Scentsy just makes sense.
