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 originating business. However, you may contact Stay Ready Outdoors at info@stayreadyoutdoors.com for assistance facilitating a return or exchange.

Customer Responsibility for Shipping Costs
Shipping cost responsibility 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 once the original is received and inspected, following the vendor’s policy.

Refunds
If a refund is approved after inspection, the originating business will notify Stay Ready Outdoors and the refund will be processed to the original payment method.

Price Changes
Prices for Shopify Collective products 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 return shipping costs unless otherwise stated by the vendor.

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


Exchanges

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

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.
