All my auction items are also available in "Buy-it-Now" listings, with same title. Search my listings for title keywords. If sold out, contact seller. This is the ONLY way to obtain additional quantities. For Tracked / Insured / Expedited shipping , must choose "OTHER" shipping option at checkout. You will receive my shipping / confirmation emails through eBay and Paypal. I do not SPAM you with redundant emails. SHIPPING: All buyers who have time constraints (or need their item "ASAP" ) , must select the Premium shipping option ( this is the more expensive option on the menu -- "OTHER") -- Otherwise, you have kept the default Snail Mail, and have decided time does not matter to you. Buyers intending to ask about a tracking number need to select the premium shipping option ( this is the more expensive option on the menu -- "OTHER") --otherwise no need to inquire about tracking NR: -- you have refused it. Basic shipping is by USPS Snail Mail. USPS provides NO guaranteed delivery dates, and may experience delays that are not under seller's control. If you have any time constraints, or would like tracking, please contact seller for additional shipping options, before making payment. I do not offer any shipping options that have specific or guaranteed delivery dates. CHECKOUT: If you only bought one item, or several lots of the same item number, then you can complete Automated Checkout. eBay usually calculates the total correctly. If you have multiple item numbers in your basket, then requesting total from seller is advantageous, as it will often result in lower combined S&H. I can only ship to your Paypal confirmed and verified address. Do not ask for shipment to a different address. Change your address in Paypal before transacting if you need alternate destination. Do not provide a shipping address in an email. YOUR ITEM WILL STILL GO TO THE PAYPAL CONFIRMED ADDRESS. This is eBay policy. If your name with eBay is different than your name in Paypal, this may cause a delay in processing your order. EMAIL You will receive my confirmation emails from eBay and Paypal. When you get the Paypal shipping confirmation, your item has shipped. This is all the email you will get. I focus my work on carefully packing and protecting parts in ESD-safe ways, NOT on spamming everybody with redundant emails. Reading all emails from eBay and Paypal, will provide an answer to the question "did you ship my item?" Check your SPAM folder to make sure you have read all emails from eBay and Paypal; they are sent on MY behalf, with information I provide. Each member is responsible to maintain a valid and DELIVERABLE email address with eBay at all times. You must disable all filters for this mailbox, since recipient is legally responsible for any mail he missed due to filtering, as recipient is in control of that filtering. If your mailbox is refusing, filtering or otherwise interfering with email sent to you, I will not re-attempt sending, nor will I jump through hoops to get mail to you. The foregoing is eBay policy. COMBINED S&H I will combine winnings for up to 7 days, contact me if you need more time. Item with highest S&H pays its full S&H. Additional lots of SAME item Number have S&H discounted 60-90% . Additional lots of a DIFFERENT item number have their S&H discounted 50-70%. Heavy items like transformers, motors, ferrites, are an exception to this. To COMBINE, you must make a SINGLE PAYMENT. You must ignore all invoices you get, (7 days max) and request total through the eBay message System --"Ask Seller a Question". Making multiple payment prevents combining orders. INTERNATIONAL I do not ship internationally if you want shipping that's fast and cheap - there is no such thing from the US. US has some of the highest international shipping rates anywhere; if this is unacceptable to you, then I do not ship internationally. YOU MUST CHOOSE "OTHER" SHIPPING METHOD IF YOU WANT ME TO BE RESPONSIBLE FOR LOST PACKAGE International delivery can sometimes experience long delays ( 4 weeks and more ), which are obviously NOT under my control. Every case is different, one item can take 2 days another 2 months. Customs inspections can cause unexplained delays. If this is unacceptable to you, then I officially cannot and do not ship internationally. International shipments over $35 total require INSURANCE, and that means REGISTERED AirMail, ( + $14 additional ). This is my actual cost, not a surcharge . Must choose "OTHER" shipping option at checkout, or your payment will be refunded. Paypal REQUIRES tracked shipping, and this is the minimal option acceptable to Paypal. See Combined item S&H savings here IMPORTANT: Buyer controls combining of order, by making a single payment for all items. Multiple payments void any shipping discounts. Can only combine BEFORE payment, never after. How to combine orders. If you have ANY time constraints, contact seller BEFORE buying or bidding, so we can BOTH come to an agreement. INTERNATIONAL shipments will NOT have online tracking , unless you use REGISTERED MAIL -- contact seller for invoice. INTERNATIONAL transit time can be 6-28 business days, and can be delayed by local Customs backlogs. If this is not acceptable, we cannot not enter into any trade. US shipments can take 5-7 business days - however the USPS does NOT guarantee these transit times, and can exceed them. eBay tracking info has 24-48 hrs update latency and can only guarantee a delivery scan -- interim scans may not occur. ALL items shipped to buyer's Registered eBay shipping address address, without exception. We can never take an address from email. Payment closes order. No changes are possible once paid. We have no expedited shipping service outside USA -- If urgent, please source locally. supreme supremewidgets supremeauctiononlinesoftware.widgets.EbayGalleryZ.swf supremewidgets supremeauctiononlinesoftware.widgets.GalleryCat.swf supremewidgets supremeauctiononlinesoftware.widgets.FeedbackWidgetBasic.swf
