Imagine we have this website.

now let’s try to order the jacket.

Now let’s apply the copoun we go.

let’s go to burp and try to apply the copoun one more time and see if that works.

Unforcenatly we got Coupon already applied.

now let’s search for another functionality in the application.

Let’s sign up as newsletter.

now we have another copoun.

let’s go and apply it.

Notice that the copoun removed 401$ from the price.

Now what if we can apply the old copoun again?

let’s try it.
