She told staff she would pay for the items, but left the store empty-handed.
Store security approached her outside where she became verbally abusive and walked away.
She was located by police later and the perfume from her previous visit was found in her bag. It was not able to be resold.
Judge Adeane sentenced her to 12 months' intensive supervision with full reparation of all items, including the perfume, and toiletries taken from Hastings New World in August, a total payment of $300.
Defence counsel Jerome Webby said the reparation sought was too high, because the tester bottle of perfume wouldn't have been able to be resold even if Valentine hadn't taken it.
Adeane declined Webby's request, labelling Valentine a "practised shoplifter" who had previous convictions.
"If you walk into a shop planning on pinching something you'll be going to jail," he said.
Farmers did not respond to multiple requests for comment about the case, and its policy around 'tester' bottle thefts.
