Might be good if you don't need a refund and don't mind paying exorbitant extra fees.
Be careful using this site for Taobao shopping and use Paypal and/or credit card to protect you from their bad business practice. I tried to get a refund on a item I no longer wanted to buy. The item was a pre-order so I just had to pay for the item. As of now their refund policy states your money will return to original purchase method. That did not happen for me, they refunded it to the Yoybuy wallet and told me just to transfer it to my PayPal. That seemed suspicious to me so I contacted their online chat/help desk to request they refund me as stated in their own FAQ. They were no help and tried to persuade me to transfer from the Yoybuy wallet to my papal. I still didn't trust it, and looked up reviews, and found out it would be a bad choice to do as the online chat said. I contacted PayPal who had me open a dispute for the refund, as they recommend this was the best option. After a few days Yoybuy suddenly froze my account, I could no longer login and would have to contact their customer service department to fix it. Eventually PayPal was able to help me get my refund. Also unrelated to my refund compared to other Taobao services Yoybuy adds on way more additional service fees than other sites.
