Ok, is there anyone who knows this person (past host, friends at party that she bought the product) that you can contact to try to get in touch w/ her?
If so, try that route and give her a call, or better yet, send her a letter (certified) explaining that after all these months you felt it necessary to receive payment for the products that she took and promised to pay for, but never did. If it is weighing on you that much. If there is no way to reach her, I'd let it go until she got in touch with YOU. Was it a debit card out of checking or a credit card? I can't remember if you stated that.
