Ans: It depends on the type of coupon you are using. If you lose a paper coupon, you’re unlucky unless you find the same coupon somewhere else. If you lose a printable coupon, just go back to the website where you printed out the original coupon and print it again. If you’re trying to use an online coupon, you can’t really lose it since it’s not a physical piece of paper. You can forget or misplace the promotional code. If this happens, return to the website where you found the code and simply write it down again.
