I don't know how they knew.

They seem to think that I'm a collector of coffee machines having bought one.

[Ashy]

Yes, some coffee to put in it perhaps, but more coffee makers, rather unlikely.

[klondike]

It's the same with most stuff though - they keep on showing you more of the same. Annoying if you see a better deal or they've dropped the price.

I only looked at some children's books ... online..
Can't get rid of them asking if I would like Percy Pig goes on a Picnic... and others..

[Ashy]

I feel sure that, if that were me, they would be offering me a pigsty and a subscription to pig food, a book about pigs and a policeman's uniform.

I now find eBay thinks I may be a collector of masthead amplifier power supplies, having had one fail in August after 18 years in continuous service.

Metal sheds keep popping up for me 

[Ashy]

I'd be more likely to buy a shed, still pretty unlikely at present, although I just bought a small tent in case it gets really cold this winter.
