What to Look for in a Listing

When reviewing a listing, pay attention to expiration date (most dispensable stock needs 60 or more days), lot number (required for DSCSA documentation), packaging condition notes, quantity minimums, and whether the seller accepts partial fills. InStockRx shows the NADAC reference price alongside every listing so you can quickly assess whether the seller's ask is competitive relative to national average acquisition costs.

Making Cash Offers

If a listing is marked open to offers, you can submit a cash offer below the list price. Enter your offered price per unit and an optional note to the seller, for example, a partial fill request or timing requirement. Sellers typically respond within 1 business day. You can make offers on multiple listings simultaneously and track all pending offers in your dashboard.

If a seller counters your offer, you'll receive a notification and can accept, counter again, or decline. The entire negotiation stays within InStockRx. No phone calls, no back-and-forth emails, no guessing when you'll hear back. Everything is documented and timestamped.

Your full DSCSA T3 documentation (Transaction Information, Transaction History, Transaction Statement) is available for download as soon as the transaction is confirmed. No waiting for paperwork to arrive by mail or email. No chasing down a seller for compliance records. Everything you need for your audit file is ready instantly.

Frequently Asked Questions

Searching the InStockRx Marketplace

You have a few ways to find what you need. Search by NDC for an exact match, or type a drug name or strength to browse available inventory. Every listing shows the package size, quantity available, and expiration date, plus the seller's verified pharmacy status. You know exactly what you're getting before you commit to anything.

Filter by expiration window, quantity, and packaging to narrow things down quickly. Every seller on InStockRx is a licensed, verified pharmacy. You're not buying from some unknown third party. You're buying from another pharmacist who operates under the same regulations you do.

Offer vs. Buy Now: Which One to Use

When you find a listing, you have two options. Buy Now purchases at the seller's listed price and starts the transaction right away. Use it when you need something quickly or when the price is already fair. Make an Offer lets you propose a lower price, request a partial fill, or add a note about timing. Sellers typically respond within a few hours.

If you only need part of a listing, say 30 units from a lot of 100, the offer system is the way to go. Just note your requested quantity and the seller can accept, counter, or split the lot. That kind of flexibility doesn't exist in a standard wholesaler order.
