Volvo S90 competitor offer?

Does anyone have any info on when this ends? My original plan was to find an S90 for my younger brother but he’s decided to keep his Tacoma. My C300 lease ends this June and my plan was to move to a V90 or S90 and sadly two days before the month ends I just found out that deal was available and dealers within 100 miles of me have nothing in stock…

Would also like to know if the 8k in cash on the 17’s stack with the trucar instant rebate barcode?
