Common Questions About Bidding in Our Online Auctions
Whether you’re a first-time bidder or an experienced participant, you might have some questions about how to bid and what to expect. Here, we’ve answered some of the most frequently asked questions to help make your auction experience seamless and enjoyable.
When is the next online auction?
Visit our auctions schedule for information on our current and upcoming online auctions.
Do I need an account to bid?
Yes - you’ll need a free account on Invaluable.com to register and place bids.
Registration is quick and straightforward. Just click “Register” on the Invaluable website, complete your profile, and you’ll be ready to bid in any of our upcoming live auctions.
Why do I need to provide credit card information?
When you create an account on LiveAuctioneers, you’ll be asked to securely enter your credit card details.
This is a standard part of the registration process. It helps verify your identity as a bidder and streamlines payment if you win an item.
Your information is encrypted and never shared with the auction house unless you authorize payment through the platform.
Can I bid over the phone?
Our auctions are online-only sales, so we don’t offer phone bidding.
All bids must be placed through Invaluable.com or the Invaluable mobile app. The process is easy, secure, and allows you to bid at your convenience—whether days in advance or right as the auction ends.
Do you offer in-house shipping?
Yes, we offer in-house shipping for all auction items! We use UPS, USPS and upon request, FedEx and ship to customers all over the world.
Your auction wins will be carefully packed with high quality materials for safe transportation.
As soon as your package goes out, you’ll receive an automated email with the tracking details.
Can I preview lots in person?
No, our auctions are exclusively online. We are based in Phoenix, Arizona and do not have a public storefront.
Should you require additional information, high resolution photos, scans or even video, you are welcome to inquire about any item offered at auction and we’d be happy to provide as much information as you’d like.
How does registration approval work?
When you register to bid, we review your account to ensure eligibility. Approval is granted to users with positive feedback and a good payment history. However, accounts with multiple strikes or significant negative feedback may not be approved. You will receive an email notifying you of your approval status once the review is complete.
What types of payment are accepted?
We accept all major credit cards, ACH bank transfers, wire transfers, checks and PayPal.
