You can use them during the timeframe on the back of the bucks, for something costing at least $28. Bonus bucks can be redeemed for up to half the price of something.
Hello Elizabeth you can use them all at once up to half of any purchase. They do not expire so if you miss the upcoming dates of April 1-15th you can always use them in July, September or December. Thank you for the response Nikki B.
