How Can I Reddem My Amazon Vouchers?

I'm guessing you mean Amazon electronic "gift cards," perhaps awarded in return for activity on HelpOwl.com. When you place an Amazon order while you have a gift card balance credited to the same email address, Amazon will ask you whether you want to use your gift card balance. That's all there is to it.

(If that's not your issue, please resubmit or consult Amazon. For the latter, call 866 216 1072 at any day or time.)
