I would be surprised if anyone knows to what you are referring. Can you rephrase your question?
Biscuit reward? What? and....do you mean 250 dollars off? Off of what?
Do you have a tax question? What is your question?
This is a message forum, not live chat. You have to post all the details of your question and wait for someone to respond.
All income taxable unless you know it isn't (specifically exempt by law).
Discounts, coupons, rebates are not income. They're just a price reduction for the item you purchased.
