Prospective offerors must submit a responsive quote on company letterhead with detailed line-item pricing, CAGE code, and estimated delivery dates, valid for 90 days. A signed SF-1449 with pricing and required clauses must be returned, and all offerors must be registered in SAM. The government seeks additional discounts, and offers must comply with all instructions to avoid being deemed non-responsive. Technical substitutions are not allowed, but the items are not brand-specific; if offering other than specified products, technical specifications must be provided for evaluation. Quotes should not cover only a single lot and must include company and point-of-contact information.
