For example, John will get a $25 discount off his order of $130. And upon receipt of merchandise, he will be given another coupon of the same amount, which can be used in his next order or be given to friends if he likes. This new coupon is one-off discount with no minimum spending requirement.
For order over $80, you can get $15 off, and another $15 coupon upon receipt of merchandise. For order over $200, the same rule applies, $40 discount when check out, $40 upon receipt.
