This is just one example that happens to be on the Big W website.
A 2TB no name portable SSD for $87 before delivery.
Two of the images have a large "16TB" stamped on the product.
I know Big W are not the seller, and probably have no liability whatsoever for any third party items listed on their site, but someone purchasing this item is likely doing so due to some level of brand recognition with the Big W name.
I recently purchased a USB hub from JB Hi-Fi market place that didn't even come close to matching the claimed specifications. Sure I got my money back, but not after waiting 90 minutes to get a JB Hi-Fi customer service person to raise a return authorisation, and then a further month until getting my payment credited.
It seems big retailers with market place offerings are side stepping any consumer obligations they would normally have, while getting a part of the selling profit regardless. There should be some duty of care on their part.
Product images 2 - 4 aren't even in clear resolution.
Is their website managed by a teen aged kid in his bedroom getting paid $12 per hour?
While I largely agree with the sentiment, how is it practically possible for the marketplace provider to actually check and confirm each listing, and to a further extent also ensure what’s delivered matches what’s advertised? As you did say in your post you did get a refund in the end albeit with a big waste of time. Is it really different to dealing with the OG marketplace, eBay? Where’s the outrage on no duty of care from eBay?
