An unexpected shortage of merchandise from Disney's hit animated film "Frozen" has created a frenzy among some parents, with one Toronto woman finding herself on the receiving end of hateful comments for selling what's become a very hot commodity.  

Dayna Herman-Cohen, the mother to a five-year-old daughter who's a huge "Frozen" fan, said she was stunned over the anger expressed by some parents after she sold a dress modelled after the "Frozen" character Elsa to the highest bidder.

"I was shocked there would be so many moms outraged at what I was doing," Herman-Cohen told CTVNews.ca on Tuesday.

"I'm being compared to the devil, it's pretty bad."

Herman-Cohen said she had searched for the dress for upwards of five months, calling the Disney Store about once a week with no luck.

During a trip to New York City this past weekend, Herman-Cohen and her mother-in-law entered a raffle at a Disney Store for a chance to purchase an elusive Elsa dress, and they both won.

Not needing the second dress, for which she paid about US $50, she posted it on Facebook but was overwhelmed by the interest from her friends.

"I didn't want to pick and choose between friends, so I figured I'd put it on the mommy group and I will give it to the person who makes the best offer."

She received offers for as low as $5, but ended up selling it for $115 via Pink and Blue, a closed Facebook group linked to an online magazine for parents.

Herman-Cohen said she received about 400 comments on the post, with many criticizing her for making a profit.

"Some people had no issue with what I was doing, and then a lot of angry people were saying 'how dare you, you selfish, greedy blah blah blah…"

Herman-Cohen has since deleted the post and removed herself from the group.

"I wish we hadn't bought the second dress to be honest," she said.

But she said her daughter is "beyond appreciative," for the dress.

The editor-and-chief of Pink and Blue magazine apologized to Herman-Cohen via the Facebook page on Wednesday.

"I am shocked and still trying to understand why Dayna received such negative comments," Nicole Bloomberg wrote. "Please choose your words wisely and be nice to one another."

Disney working 'around the clock' to restock merchandise

The "Frozen" dress has caused a frenzy, as parents struggle to find the sought-after costume that’s in short supply.

Disney says it's working "around the clock" to get "Frozen" products back on store shelves, and that a "limited quantity" of the merchandise is being replenished in stores.

"'Frozen' is a global phenomenon that has truly exceeded expectations on every level,” Margita Thompson, vice president for external communications with Disney Consumer Products, said in a statement to CTVNews.ca.

The company recently implemented a new system that caps the amount of "Frozen" merchandise customers in the U.S. and in Canada can buy in stores and online.

The only way to secure an Elsa costume from the store is via a raffle held at certain locations on Saturday mornings.

In a statement, the company said it anticipates that "Frozen" products will be back in stock in July or August.

In the interim, parents are getting creative. One Facebook page "Frozen Finds" helps fans of the movie find scarce merchandise and serves as a forum for sellers to post their products.

Meanwhile, authentic Disney limited edition versions of the dress are being offered on eBay for as much as US $1,200 while custom-made versions of the dress are running for more than $2,000 on Etsy.com.

Herman-Cohen said if really wanted to make a profit, she would have sold the dress on eBay.

"It's unfortunate it's come to this," she said.

"It's sad when a company as big as Disney has a movie that's a number one hit, and has a song that's an Academy Award winner, and the costume goes along with it is unavailable. It's actually quite pathetic in my opinion."

"Frozen" opened in November 2013 and went on to become the top-grossing animated film of all time, attaining total revenues of $1.07 billion worldwide after 19 weeks in theaters.
