IF you have a kid under the age of 10, you're probably familiar with Woolworths' latest collector craze: Marvel Super Discs.
They're basically pieces of collectable plastic featuring a Marvel comic character - and there are 42 to collect.
But some parents are taking the collecting very, very seriously. On eBay, the disc considered 'rare' are selling for up to $800 so kids can complete their set.
It's infuriating other collectors, who think that other parents hoarding the 'good' discs are making it harder for others.
"What is going on with having some so rare that they can go on eBay for $90?" asked one irate mother. "Do mums not have enough to do without having to come to swaps and/or organise our own? Then there's the added cost of posting them across the country at times too."
Others have accused the supermarket giant of deliberately making too few of the coveted collectables.
One mum swears Woolworths staff are hiding the rarer disks to encourage more spending - something Woolworths says they are doing everything to safeguard against.
"I think its sad that Woolworths have released that many Marvel discs yet have made it real hard to complete sets. Lots of unhappy children," wrote one disgruntled mum.
"Some people are disgusting," wrote mum of an eBay post selling a rare disc for $800. "I hope no one bids on this."
Most mums are contenting themselves with swapping the discs they have with ones they need to collect, with swap sites popping up all over Facebook.
But Woolworths says the store is doing everything they can to distribute the discs fairly.
A Woolworths spokesperson told Kidspot:
"Our Marvel Heroes promotion is incredibly popular and we are delighted with the response we have received.
We work closely with stores throughout the country to ensure appropriate processes are followed when issuing the discs and to ensure our customers have the best opportunity to collect the entire set.
Likewise, we take the selling of these discs and merchandising on eBay seriously and are making every effort to investigate this.
We encourage customers to keep collecting while stocks last and swapping with family, friends and Facebook swap groups, of which there are many."
The store also pointed out that the 'rare' discs are more plentiful than people realise.
"The discs that have been reported as being 'rare' are actually more plentiful than you think," the company wrote on its Facebook page. "Each has over 1 million in circulation."
Mums who haven't caught the Marvel disc craze are bemused at its popularity.
"I'm shocked that people are BUYING these things," said one. "They're FREE, people!! And if your kid doesn't get the whole collection, then that's a lesson learnt, not a reason to turn to the black market of supermarket collectibles!"
"Just accept what you end up with and move on with your lives," laughed another mum. "Your kids will have to learn how to deal with a bit of disappointment now and then."
