@John_Lesio Our Open Box policy states -
Open Box (and Used) merchandise are products that have been purchased and delivered to other customers, and then returned to GigaParts. Open Box and Used products are typically sold under cost. GigaParts tests Open Box and Used products for basic functionality only.
Due to the varying quality of products returned to GigaParts, regardless of what the product description says, GigaParts only guarantees that you will receive the product itself, accessories may or may not be included. Bear in mind that your open box, used, or refurbished product may not contain microphones, cables, adaptors, manuals, CDs, drivers, fans, etc. Additionally, the product may exhibit cosmetic imperfections as a result of its having been previously opened. GigaParts will not send you any missing accessory, even if the accessory is required in order to properly make use of all the product’s advertised functions. While GigaParts does not like to discourage sales, please purchase open box, used, or refurbished products only if you know how to deal with potential missing accessories.
