Everything Must Go Pricing
These aren't regular sale prices - this is genuine "moving warehouse" pricing. Discounts you simply won't find under normal retail circumstances.
Trade Show Display Models
Many items are pristine display models from major audio trade shows - equipment that's been seen but never installed. These pieces often include special editions or limited releases not available through regular retail channels.

What types of items are included in the relocation sale?

Can I return or exchange relocation sale items?
All relocation sale items are sold as-is with no returns or exchanges. We encourage local pickup customers to inspect items before purchasing.
