I will gladly combine shipping for you on multiple items. Either request an invoice be sent or I will refund you the difference in shipping prior to your order being sent.
Orders that exceed $20 will sent Ground Advantage.
eBay Standard Envelope (USPS First Class) quotes 3-6 day delivery but I have found that sometimes the actual transit time exceeds this. Also the tracking on these is often hit or miss. You can always choose Ground Advantage if you'd like a quicker transit time and better detailed tracking info.
Thank you for your support. Please reach out if you have any questions.
