Saw this in my local newspaper the other day. Late last month, they sent me an email with this, I thought it was a targeted offer but after seeing this, I guess not.
Buy $175 to get $100 off. Free delivery
Code ends 12th May or first 1000 customers.
Offer only valid for postcodes
2046,2038,2193, 2131,2041,2137,2134,2136,2138,2132,2133,2047,2203,2042,2045,2140,2040,2049,2204,2039,2044,2048,2135,2130
enjoy
I can confirm this code is NOT valid for postcode 2121 - which is consistent with what the OP says in their post….
Good deal if you live in the right post code.
