Buying a bag of goods without knowing its contents
Q: There is a app called Refreshi, this is how it works, you pay a certain amount and get a bag of food/dessert etc... but you don't know exactly what. This is how it is written.
"Enjoy a tasty mix of baked goods. R68 You could receive, donuts, croissants, danishes, and/or pastries. Every bag is a surprise and delight to your tastebuds."
Is this permissible?
