SHIPPING:
Most fixed shipping and free shipping rates on eBay ads only apply to the lower 48 states. Shipments to Alaska, Hawaii, APOs, Puerto Rico, Guam and international locations may have additional shipping costs and delays. Some items can not be sent to California or may have delayed shipping. Please contact us for more information. Many of our products are shipped via USPS. Please be aware that USPS does not always scan their packages so the tracking number may not have any information until it is delivered. Our parcels are picked up by USPS the same date or the next postal service day that the tracking number shows being generated. Also, many of our items are drop-shipped directly from our suppliers and not from our store location in Vancouver, WA.
If you have a po box, please provide BOTH the po box and physical street address

COMBINED SHIPPING DISCOUNTS
For multiple quantities of the same item, just change the quantity in the box next to "Buy It Now" and eBay will automatically calculate the discount. For combined orders with different items, use "Buy it Now" and then "continue shopping" on each item and then prior to completing the payment, use the "request a total from seller" link in checkout and we will adjust the shipping total and send you a new invoice. If multiple item numbers are purchased and paid without using "request a total from seller", a combined shipping discount will not be offered in a refund form. Multiple items must be paid in a single payment in order to qualify for a shipping discount.
