I am a merchant with Spring and they provide the worst partner and merchant experience that we have ever received. They treat you poorly, and do not provide you any support when you need help. They do not honor your own sales policies regarding your own product, and try to dictate to you how you need to handle returns, and deduct funds from your account for returns that you never received and were never authorized in the first place. They do not respect their merchants, and only pay attention if you are selling large volumes with them. Otherwise, you are treated like garbage. Do not sell on their website, you will regret it. You have been warned! 0 Stars.
