Er, maybe a marginally more diverse selection, but half of that stuff has been sold on TJC for years. They'd get a lot in, sell it ad infinitum, then it disappears. Once they got IW they just shifted most of that stuff over to there. I'm not sure that means "somebody" has changed their approach to stock acquisition.
Don't get carried away by seeing a few familiar brand names. IW3 isn't now striking deals with brands and using major suppliers. like IW2 did. It's the same model TJC has used for years (and why they're profitable): buy cheap, buy direct, buy clearance stock.
When Wilko's went to the wall, IW3 had a show selling Wilko's branded something or other (can't remember what it was now - wipes? might've been wipes).
If they're doing a Slazenger, Xenta, or Tefal show ever week for several months, selling a range of different items from those brands, and not just lots of shows selling one thing from those brands, then nothing more, that'd maybe prove me wrong…
Unless you're being satirical and I'm misreading you? I mean you do say "better quality stock items" after referencing tin jewellery boxes and billy no-brand 0.3MP security cameras sending who-knows-what back to where once it gets access to your home wi-fi…
But if people are happy paying £40 in 2024 a white-label soundbar made in 2012 with worse sound quality than most Poundland headphones, rock on - things are only worth what people are willing to pay after all, and it's why this channel remains profitable.
