I think of it this way: each wash is $12.99, so a $200 prepaid card would give me just over 15 washes in 95 daysprotege2k wrote: ↑Nov 22nd, 2016 7:45 amor, $200 / 95 days = $2.10 / day vs $180/90 days = $2 / day. Depends how you want to look at it....
I used the app for shell last year and it's very unreliable (perhaps just for the shell location I went to). The worst thing is wasting 20 min (or more) lining up, only to have the app not work, annoy everyone else that's lined up behind you while you fiddle with the app, then having to maneuver your car out of the car wash line (if even possible - though most wash stations should have an escape path).
pretty sure that I'd put my car through 15 washes in 95 days
the rest is bonus for my friends and family
the card is a huge convenient, a time saver versus having to buy a wash everytime
