Plusnet router return?

[#1]

I'm upgrading to fibre shortly, and have already received a Plusnet Hub One (the day after ordering fibre, in fact - hope the actual fibre changeover is as efficient!). My Technicolor 582n ADSL router (which I have never taken out of its box, preferring to use my own router instead) is therefore surplus to requirements; and I wondered if Plusnet have any arrangements for customers to return unwanted routers? It seems a shame just to put it in the recycling bin.

Sell on eBay?

Offer on local recycling group.

Give to a charity that accepts electrical items, in my area British Heart Foundation has a dedicated electrical and furniture store.

All good ideas, but the router is really only of use to a Plusnet ADSL customer - the sort of person who can unlock it for use with another ISP probably has their own router anyway!
