Traveling to the UK and would like to purchase something one ebay.co.uk - Are there lockers/shipping centers I can have the item shipped to?

I will be traveling in the UK and wanted to buy some items from ebay.co.uk.

Typically I would try to pick up in person, but that ends up limiting my options, since I would have to find a seller that's relatively close to where I'll be staying or traveling to/from along the way.

I am looking for suggestions on companies I can search up online or maybe some key words to use as a starting point to see if there are any in the areas that I'll be staying in.

Ones I've found from searching is

https://www.postoffice.co.uk/mail/poste-restante

https://www.ukpostbox.com/address/uk-parcel-address

and mentions of collection points, but no specific company or website to find more info on this at?
