I got a coupon from buying something but when I typed it into copy and pasted it into the coupon section it says I can't use it, it's not out of date it goes out of date the 13th 8:30 UTC and I haven't used it yes can I have a new coupon or can this one somehow be fixed
Usually this happens when another purchase is made for that account before you use up the code. A new code is generated and emailed to whoever bought it, and the previous one gets automatically invalidated.
