Walking past Flinders St. station in Melbourne this arvo' when given a gift card for $20 off first purchase. Actually I was handed several of these while trying to get back to work, all have the same code so clearly not unique.
Just got something on clearance (some good items around or under $20), so no minimum spend (you do need to pay shipping costs however which seem to start at $7.95)
New code 20ACTklY9MW @ 8/5 Thanks to BelowSubZero
New Code 20ACTImN24S via feezfun
Edit @ 25/7: PER20MW38JL, BRS20wpUlaY, PER20Ae2CJo, PER20MMeq1X Codes ADDED.
