Mark your calendars! To celebrate the Costco Bonus Auctions Event event, Costco is running a week full of bonus auctions from Monday, July 11 until Friday, July 15.

If your business specializes in resale and looks to liquidation as a steady source of inventory, then now is the time to start preparing for the summer months ahead.

How It Works

With this increase in listings, this is the perfect time to take advantage of Costco’s Truckload Discount Savings program. This program allows you to save on shipping when you buy 20 pallets or more within 48 hours shipping out of the same warehouse! Check the link for more details.
