Screwfix do this too. Just a counter with a handful of staff who go and get your items.

If you pre-order it's waiting at the desk. Very handy for people who can order from the job site on the account and send the lad round to grab it.

And a (relatively) unshittified website too because if jobbing tradies can't use the damn thing because it's too loaded down with ads and bullshit, they just won't.

Screwfix is an all-round excellent consumer experience, for DIY or trade. The reviews on the website are often hilarious as well.
