Please note that other items (such as consoles, games, controllers, disposable batteries, CDs, DVDs, cassettes, other media, stands, mannequin parts, shoe trees, rulers/items for scale, and/or other accessories) appearing in the pictures and/or video are solely for demonstrative/display purposes and are not included with the listed item. Vintage items are, by definition, 20+ years old. Even unused vintage items, such as new old stock, can experience natural degradation over time. Electronics, for example, often contain capacitors that may deteriorate. Buyers should understand that vintage items can fail at any time and may require servicing when put into use. Items listed as 'Tested' undergo basic power on/off cycles and evaluation of their most fundamental functions. However, complex features and devices with multiple ports are not fully tested in all possible scenarios. When using analog media players such as VCRs and audio cassette players, there is always a risk of media damage, including tape jams or deterioration. We strongly advise buyers to test the player with non-valuable, replaceable media first before using any prized or irreplaceable tapes. Attempts to claim damage as a means of deception will not be entertained. Items listed as 'Untested' have not been tested in any capacity unless otherwise stated in the listing. These items should be assumed to be non-functional, in need of repair, or suitable for parts only. Items may be shipped in separate packages to reduce shipping costs and/or comply with weight limitations. Items priced at $400 and above will require an adult signature upon delivery. Please plan accordingly. We take pride in our commitment to environmental responsibility by reusing packaging materials. This not only helps reduce our ecological footprint but also allows us to provide cost savings to our valued customers.
