Damaged, Defective, or Incorrect Items

Please inspect your order upon arrival. If your item is damaged, defective, or incorrect, contact us at crquarto@stayreadyoutdoors.com within 7 days so we can evaluate and resolve the issue promptly.


Non-Returnable Items & Exceptions

Some items are non-returnable, including:

  • Sale items (these sales are final)

  • Gift cards

  • Engraved or customized items

  • Perishable goods (e.g., food)

  • Personal care items (e.g., hygiene or beauty products)

  • Hazardous materials (e.g., flammable liquids or gases)


Food or Drink Products – All Sales Final

Due to the nature of long-term food storage, all sales on food or drink products are final. We do not accept returns or exchanges on food or drink products for any reason including incorrect order, change of mind, or shipping delays. Replacements will only be issued in the event of a verified manufacturing defect or shipping damage, which must be reported within 5 days of delivery with supporting photo documentation.


Products Fulfilled via Shopify Collective

Some items sold by Stay Ready Outdoors are fulfilled by third-party vendors through Shopify Collective. These items follow slightly different return procedures:

  • Return Window – Returns must be initiated within 30 days of the purchase date.

  • Who Handles the Return – Returns and exchanges for these products are handled directly by the business from which the product originated. However, please do not hesitate to contact Stay Ready Outdoors at crquarto@stayreadyoutdoors.com if you need help facilitating a return or exchange — we’re happy to assist.

  • Customer Responsibility for Shipping Costs – Shipping cost responsibility for returns and exchanges varies by vendor. Some vendors offer free returns or exchanges, while others may require customers to pay return shipping.

  • Size Exchanges – If a return is for a size exchange only, the replacement item will be shipped back to the customer once the original is received and inspected, following the vendor’s policy.

  • Refunds – If a refund is due after inspection, the originating business will notify Stay Ready Outdoors and the refund will be processed back to the customer’s original payment method.

  • Price Changes – Prices for products fulfilled via Shopify Collective are subject to change without notice.

Vendor-Specific Note:

  • The Buffalo Wool Company – Items fulfilled by The Buffalo Wool Company through Shopify Collective follow the same return procedures listed above. Customers are responsible for the cost of shipping items back for return or exchange.

All other eligibility requirements and non-returnable item restrictions in our standard policy still apply unless otherwise stated above.


Exchanges

The fastest way to exchange an item is to initiate a return for the original item and, once the return is accepted, place a new, separate order for the item you want.


European Union Customers – 14-Day Cooling-Off Period

If your order was shipped to the European Union, you have the right to cancel or return it within 14 days of delivery, for any reason. To be eligible, items must be unused, with original tags and packaging, and include proof of purchase.


Refunds

Once we receive and inspect your return, we will notify you of its approval. If approved, we will issue a refund to your original payment method within 10 business days, less the cost of return shipping.

Please Note:

  • It may take additional time for your bank or credit card company to process and post the refund.

  • If you haven’t received your refund within 15 business days of our approval, please contact us at crquarto@stayreadyoutdoors.com.
