The topic at hand is about finding affordable sources for extra ostomy supplies. Many people with ostomies face the challenge of their insurance only covering a limited number of supplies each month, which can lead to running out. Here are some helpful tips and insights for finding lower-cost options:

1. Online Discount Suppliers:
- Medical Monks is frequently mentioned as having the lowest overall prices and is reliable for both ostomy and wound-care items.
- Best Buy Medical Supplies is noted for offering the cheapest pouches and barrier rings when you exceed your insurance limit.
- ExpressMed is used for Hollister M9 odor-control drops and adhesive-remover wipes. They have a rewards-point system, widespread U.S. warehouses, and offer free shipping above a minimum spend.
- ShopOstomySupplies may not be the absolute cheapest but is known for quick delivery.
- Ostogroup, based in Florida, might sell items not covered by insurance (except bags if you have insurance). It's best to call and verify.

2. General E-commerce & Resale Options:
- Platforms like eBay, Craigslist, Facebook Marketplace, OfferUp, and Poshmark apps are reported by many to offer deep discounts or even free supplies. Always check expiration dates before purchasing.
- Reddit ostomy communities sometimes list free supplies if you cover the shipping costs.

3. Increasing Insurance Allotment / Building a Surplus:
- Ask your prescribing physician to write a prescription for more frequent barrier changes (e.g., "change every other day") or to increase the monthly number of bags (e.g., 30 instead of 20). This can lead to insurers approving a higher quantity, allowing you to stockpile.

4. Free / Donated Supplies:
- Request free samples directly from manufacturers like Hollister, Coloplast, and ConvaTec.
- Local ostomy support groups and nonprofits often have "donation closets" where you can pick up supplies during meetings.

5. Stretching Current Supplies:
- Users of a 2-piece Hollister system report safely wearing one wafer for up to 10 days, typically a week, while changing and rinsing pouches for reuse.
- Shower with the pouch on, dry it, and then use a blow-dryer before reattaching.
- Ensure flanges are clean to maintain a reliable seal and extend wear time.

6. Fast but Higher-Priced Option:
- Amazon is useful for next-day delivery when something is needed immediately, though it comes at a full price.

These tips can help manage the cost and availability of ostomy supplies, ensuring you have what you need when you need it.
