I paid 40 Euros in 2022, so 45 sounds about right. I did have to pay a small fee (5 Euros or so) at the drop off point. I could have arranged pick up at my hotel, but I felt better handing my suitcase over at their drop off place rather than wondering if it had been picked up after I started walking.
Unfortunately, I didn't make it to Santiago that year, as I broke my wrist just north of Porto. But I contacted Luggage Driver, and they retrieved my suitcase from the Loop Inn and delivered it to where I was staying in Matosinhos (for an additional fee of course).
I have picked up a bag from the Loop Inn in the past (including last year), because that's where Express Bourricot, the company that ships bags to Santiago from SJPdP sends them. It's very convenient because they have a 24 hour reception desk, so you can pick up your bag whenever you want. I think that they may charge you a small pick up fee too. They don't when you ship with Express Bourricot, but I'm not sure that they have the same arrangement with Luggage Driver.
Edited to add: I just looked through my emails, and when I had the bag re-delivered to Matosinhos I was charged 40 Euros plus 5 Euros for storage at Loop Inn - total $45 Euros.
