UK toy retailers are left scratching their heads and fear missing out due to lack of availability of key lines.
With reports of Frozen dresses selling on eBay for up to £600 in the national media, toy retailers are asking: where has all the Frozen product gone?
Following the DVD release of the 2013 animated film, sales have soared, with total spend on Elsa products reaching $3,397,816 on eBay.
And as desperate parents take to the internet to compete for the coveted collection of dresses, dolls and plush, UK toy retailers have been left scratching their heads.
"We are looking for Frozen, that's a key thing on our list, but it has been practically impossible to get hold of this year, and yet there has been massive demand for it," Helen Gourley, managing director of Dunblane-based ToyHub, told ToyNews.
"I would like to say Frozen has been one of my top products for the year, but I couldn't get any products. There's been a huge demand and we have basically been stuck with nothing." Brian Simpson, Toytown's manager and toy buyer, echoed Gourley's concerns.
"Our best selling ranges so far are undoubtedly The LEGO Movie, Minecraft and Frozen," he commented.
"It's a pity that out of these, Frozen has been so short of stock because we have seen huge sales on the other ones."
And as 'Frozen-mania' continues to rage into the second half of the year, retailers are putting the shortage down to 'overcautiousness from both Disney and the retailers.'
"Frozen has taken everybody by surprise.
"I think because Brave wasn't so big, everyone was a bit dubious about taking Frozen stock. But it has just hit everybody by surprise, because it has been so massive," Paula Leslie, manager and owner of Toy-Bocs-Teganau, explained.
"We had some Frozen products in at Christmas and they were pretty slow to start with, but as soon as the DVD came out, it became massive. I have now got a huge waiting list for the outfits."
