STAPLES B&M: HP 100 pack 16x DVD +R or -R $16.49 or less with 5 off 25 coupon

Yesterday I went to my closest store @Leesburg Pike VA 22182 for the free battery and saw this HP DVD media. They had plenty of them put along with other brands.
It appears in Staples Weekly Ad. Since it's a clearance, online shows OOS. But stock checker shows all the stores around in my area has it.
