Description from 7-11:
Slurpers! Dust off your bowls, cups and baseball caps. It's BYO Cup Day!
September signals the start of slurping season so for one day, 21 Sept, we are letting you bring in your favourite cup and fill it with Slurpee for only $2.60!
Check the rules over on the BYO Cup page (http://on.fb.me/reKnIb) and check out how you can win a whole year's worth of Slurpee!
It is from the official Slurpee Australia page.
Rules:
Any cup is fair game as long as it fits within 230x260mm. Head into store to test your cup fits.
Unless you enjoy mopping, cups must be watertight with no holes or tears.
Your cup must be clean and free of foreign matter. You don't want to ruin the taste of your Slurpee.
To prevent permanent brain freeze, only one fill up per cup is allowed.
So no point bringing in your fish tanks. :P
NIce one!!…now I want that wine glass…lol
