Just went there for the nappie deal. https://www.cheapies.nz/node/33868#comment-127479
Was a painful waiting process (about 30 minutes): the counter staff reported to the supervisor, then the store manager, then the area manager. I ended up being told that I can only get one item maximum for price match.
Have checked their policy again and it reads: The price matching policy is limited to the retail limit applicable or a maximum quantity of one of each product.
I'm pretty sure that it was three not long ago. The change has made their Price Match system more dispensable now.
Usually 3, but last time I went to Botany, they said 6. This was about 3 months ago.
