How to make a million pounds?

Am I missing something or is there a business opportunity selling Huel to idiots on eBay?

Looking at the eBay listing for Huel there seems to be people selling Huel for twice the price of buying it direct?
Most seem to advertise a single 1.7k bag and sell at or near the same price you would pay for 2 x on this site???
Others advertise both bags but for over £80? + Post??? + some of the text gives the impression of the seller being connected to Huel directly.

Other individuals who put up a single 1.7k bag for auction seem to be getting bids of over £30?

Am I just confused??

With ebay/paypal fee’s & postage.
I’d expect the margins to be minimal to be honest.
