ALL CollarSafe's items are in stock & shipped same/next BUSINESS day. ALL items ship "FREE" USPS First Class Mail with a tracking number unless you choose PRIORITY MAIL. First Class mail usually arrives within 3-10 business days. The "expected" delivery date provided to you is simply an "ESTIMATE" solely provided by eBay/USPS and is NOT always accurate and is NOT guaranteed. CollarSafe's only guarantee is that your item will ship same or next business day. If you purchase Priority Mail, your delivery guarantee, is between you and USPS and not CollarSafe. Any shipping or delivery issues/claims/refunds with USPS are the buyer's responsibility. Circumstances beyond my control, such as weather, holidays, misdirected mail, barcodes not scanning properly, etc., can cause unexpected "delays" and should be understood PRIOR to your purchase. Please contact me if you have any questions or concerns. Thank you.
