I usually ship within 2 business days after payment is made, sometimes same day. I also post positive feedback as payment is made. Payment can be made by PayPal (or any of their credit cards). If you have any questions, be sure to "ask seller a question." Be sure to check my feedbacks 100% and I intend to keep it that way.
