1.Buy 3 items and get 1 item for free when you pick 4 items within the Winter Sale Collection. Buy more save more. Buy 6 get 2, Buy 9 get 3, and so on.

2.Valid on purchase of 4 selected items in a single order. The free item is the lowest priced item.

3.When you return the item that enjoys the Buy 3 Get Extra 1 Free promotion, the returned value of each item will be calculated by taking the free item into account.

For example, if you have paid $90 ($30+$30+$30) for 3 items and got 1 item for free ($10), then the discount rate of your order = $90/($90+$10), i.e., 90%. If you want to return a $30 item, you will receive $30*90% = $27.
