bought it ...if sister can't decide what you can buy up to $780 once,
you can buy their coupon and products first time...and get the set of gift first....ie, choose two of their products are $280...and then buy 5 pcs of $100 coupons (total:$780)....those coupons are able to use within one year (use as like money)....
this method is a ba told me....
