You are reading my post - the $9.00 comes from 15% discount.
The top of the rebate form says, “…with a $50 purchase…”.
So if somebody did a transaction with HOME10 and 20% off, it will drop the price below $50. It is too late anyway for the 20% - but if somebody was buying only 1 luggage, then Home10/20% off is probably better than dealing with rebate house. But by using 15% off coupon, the discounted price is $51 - so that stays above the $50 purchase price. And the deal should still be live versus the 20% that is expired.
