Easy Returns - No Hassle Money Back Guarantee:
Our Outdoorplay Return Policy is designed to give you peace of mind, and we guarantee the quality of every product we sell. If you are not 100% satisfied with your purchase from Outdoorplay, take advantage of our “No Hassle Money Back Guarantee” and return your unused item (in its original manufacturer packaging, along with any hangtags) within 60 days of purchase to receive a refund. The item must be returned in the state you received it, in order to receive a full refund. All returns are subject to evaluation by the Returns Department.
Outdoorplay partners with Redo to offer optional Return Protection coverage at checkout. When you place your order, you can opt into Free Returns during checkout for $2.98. If you think you may need to return or exchange any part of your order later, opting into this small fee up front will cover the cost of your return shipping label. (This is a great deal since our average return shipping label is about $12!)
If you choose not to opt into the Return Protection, you will be responsible for the cost of your return shipping label. The cost of return shipping is based on the weight and size of the product you will be returning.
All sales on Used Items are final: no returns, exchanges, or refunds. Please note, we reserve the right to include a processing fee for some returns (for example, when cleaning or reboxing is required, if you refuse to receive shipment, etc.), which will be deducted from your refund. Oversized items (very large or over 50 lbs.) will require us to manually arrange return shipping.
