Reversing private APIs, Safeway, and not-so-extreme couponing

CRANK

Safeway is an American supermarket chain that has historically had a pretty comprehensive coupon program. They somewhat recently tried to modernize their offerings (as they were founded in 1915, and are pretty much the definition of “old guard” companies), by allowing online coupons. This brought what used to be a painstaking process of clipping coupons from magazines to a slightly less painful process of having to click “Add” on all the coupons every week after logging onto their site.
