I wish ebay would hide listings that are more expensive than amazon. It's extremely frustrating getting amazon packages from ebay purchases. I make sure to 1 star all of them.
3 days later the package arrived from amazon, complete with packing slip, where I found it cost £16.
Searching the sellers account they had thousands of random listings - where I assume they can leverage a small profit. Items came and went quickly from their inventory, I assume as amazon prices fluctated.
