Based on the 30 days guaranteed policy, it applies on defect/damage or filling your order. You can't order it and say "hmm...I don't want it anymore because he's too red. I'm sending it back and Sideshow must pay for all my expenses." The question is...being too red might not be considered as a "defect" to them. So, I didn't want to debate with them and fight for the ALL the shipping expenses. Therefore, I rather cancel now and re-order it down the road. Also, by cancelling now, you would be saving them money on the shipping expenses.
We will pay the return shipping cost if the return / exchange is a result of our error such as a defect / damage or an error in filling your order. * If the purchase is being returned for any other reason than those previously stated, the buyer will be responsible for all shipping charges, including those to return the item(s) to us. Refunds will be the purchase price minus any applicable shipping charges.

That applies to Sideshow covering the S&H. But you can return a piece for whatever reason within 30 days of shipping.
