Tokuya, the $2.80 store (used to be $3.50 for a while) is having a sale - everything in store is $2 + GST ($2.20) for a 'limited time only'. Melbourne CBD store (Bourke st)
See the attached PDF I received in an e-mail.
Considering everything used to be $3.50 at some point, $2 is a nice saving :)
Wouldn't everything be $2.20 since they state "2 dollars plus GST".
