I do combine shipping! For U.S. orders, add the items to your cart and request new total. Or, I can refund the extra shipping after purchase.
For international shipping (which is handled by ebay), please let me know the items you'd like to purchase so I can combine them all into one listing for combined shipping.
All PCs over $10 will have tracked package shipping. For PCs under $10, buyers can choose tracked package shipping or stamped (untracked) letters.
