I never tried BH&G and Scentsationals until recently when I received some clamshells in couple of destash boxes.
These are inexpensive ($2) and available at Walmarts.
I tried a few of the ones I received and one cube easily scents up a huge area in my experience.
-Shimmering Cherry Blossom (a soft yet potent floral. My least fave)
-Fresh Ocean Flowers (a mix of a clean laundry scent and a soft fresh floral. Very good strong scent!)
-Sugared Melon Kiwi (fresh fruity scent)
-Fragrant Evergreen Forest (a scent of spruce and/or fir trees, perfect for Xmas and winter in general)
-Hawaiian Pineapple Cilantro (a nice fresh summer scent, fruity yet refreshing)
-Timeless Devotion (floral mixed with fruit, yet a very pleasant and lovely scent! Very strong!)
-Spa (my favorite! A super fresh minty herbal and clean scent)
I am super excited as I just scored a lot of over 60 BH&G (and maybe Scentsationals?) clamshells on FB in a huge destash lot for like $1.20/each. Will post about it when I get it!
