We had a problem with a spammer abusing our Contact forms to spam our account holders, so we've disabled the forms to work on adding ReCAPTCHA to prevent such automated abuses in the future.
Until we get the Contact forms functional again, try clicking your own affiliate link to reach the merchant's site and see if you can find their contact info posted there. If they don't have any contact info posted there, send us an email, and we'll help you out:
