Daily vs. Once-per-week Shipping
You now have the option through your account profile to select Daily or Weekly (once-per-week) shipping of your winning bids. Then, bidders who win multiple items during the same period will receive REDUCED shipping charges. All such savings will be reflected on your Consolidated Order Summary Invoice.
By selecting DAILY as your shipping preference, all winning bids are shipped within 2 business days. For example, all lots closing on Monday usually ship on Tuesday. All lots closing on Friday through Sunday usually ship on Monday.
By selecting WEEKLY as your shipping preference, for lots closing the previous Thursday through Wednesday, all winning bids are shipped within 2 business days from the last lot closing on Wednesday.
Sorry, we cannot hold packages won on different invoices to be shipped together.
Changing your shipping preference does not take effect until shipments have been completed the Thursday following your change. For example, if your current preference is DAILY and you change it to WEEKLY on Friday, you will be shipped DAILY through the following Thursday.
Orders usually ship within 1-2 business-days from the receipt of your Order Summary Invoice and you can expect arrival within 2 to 8 business days, depending on your location. Shipping times are not guaranteed.
