First of all, thank you everybody for your questions and posts!
EdenFantasys is a complex store with lots of products, partners and, of course, customers hence there is no one consistent reason for each item that goes on sale.
Each sale serves different purposes and is oriented toward different demographics.
There are many things that affect items: manufacturer’s specials, item promotions, items that go slow with current price, competitor’s prices, warehouse situation and many others.
Negative review might affect how fast item sells, but not necessarily and is not the general reason for sale. Usually we try not to carry items with only bad reviews at all, although mistakes happen sometimes.
Of course Labor Day is a traditional day for Discounts and Sales across the country - you can find even new products, such as Sphere, on Labor Day Sale.
I hope I answered your questions at least partially. Please let me know if you have more questions!
Regardless the reasons – we hope you enjoy sales and promotions we run!
