A new Fortnite package was discovered in a Walmart offering for an MSI gaming laptop. The Street Ops package may include the unpublished Instinct skin.
In November 2018, NVIDIA announced the Counterattack bundle containing Reflex Skin and accompanying cosmetics. While a female variant of the skin has been datamined, it has not been published yet.
Epic Games now appears to have partnered with MSI to release a new bundle containing the feminine variant of the Counterattack Bundle cosmetics. 
The MSI GV62 Performance Gaming Laptop is available at Walmart for $ 899. It's obviously a product that works with Epic Games.
The product ships with V-Bucks and the Street Ops bundle, which includes Skin, Pickaxe, Back Bling and Glider.
