And my membership/discount card that I unearthed from the depths of my wallet and which has been unused for over twelve years not only worked at the checkout but still had my points on it from back then!!! Most businesses would have housecleaned an account that had been inactive that long ... I was quite prepared to have to re-register and start from zero.
Definitely worth the extra couple of blocks and getting across the eight-lane major street stroll. :-)
