When asked for photographic identification, she put the items to one side and said she would be back with the identification, the summary said.
She returned later that day and took similar items to the checkout, this time asking the items be put on the Patchells Industries trade account. When asked for a purchase order, she said to put it under the name "Donna", the summary said.
The items were then allowed to be bought, for a total of $114.26.
Malcolm's lawyer, Tim Braithwaite, told Judge Maree McKenzie in court on Tuesday Malcolm had found herself in a difficult position since being released from prison and had intended to pay for the items.
Braithwaite said Malcolm had said she messaged an associate at Patchell Industries and had not heard back but had decided to put the items under the name "Donna" anyway, with the intention of paying it back when she could.
Judge McKenzie said there were clearly aggravating factors, including that she was on parole at the time of the offending and that she revictimised Pearce Flooring.
She sentenced Malcolm to two months' imprisonment on each of the charges, to be served concurrently.
Maryanne Pearce from Pearce Flooring was present in court and said she had hoped Malcolm would be jailed for longer, particularly given she had not served all of her previous sentence.
"It is such a disappointing sentence, especially because she had the cheek to try it again with us. We were completely oblivious to everything she was doing to us."
She said she didn't believe "for one minute" Malcolm intended to pay back the companies for the items she was attempting to take at Bunnings.
